Duplex Tent - Holiday Sale - $25 Off
Duplex Tarp - (no screen or floor)


The Duplex Tent is the sweet spot when it comes to size, weight, and features. It has ample space for one person plus gear to spread out, or it can fit a partner. It has two doors, so you get ventilation, views, and vestibule space on both sides of the tent, plus you don't have to climb over your partner to get out.


  • Sets up with two trekking poles adjusted to around 48" (122 cm). Slightly taller or shorter fixed length poles will also work. Tent poles are also available if you don't use trekking poles.

    Eight stakes are required for this tent.
  • Any of the four storm doors can be opened or closed independently. Leave all four open on nice nights for a breeze and great views. Close the upwind doors to block cold wind, or close all four for 360° rain protection. The doors are closed with custom made metal hooks. Door hooks can also be retrofitted on any older tents.
  • The tarp overhangs the bathtub floor by 4-5 inches (12 cm). In calm rain or under wet trees one or two doors can be left open for air flow without water dripping on the floor space. In almost all conditions at least one downwind door can be left open for air.

    Tip: For even better rain protection with a door open, use the included clips to pull the screen door back away from the rain spray, as shown.
  • Rainbow zippers on both sides of the tent allow easy entry regardless of which doors are closed, and they give you access to every vestibule area.
  • This tent has a solid, sewn in 8 inch (20 cm) tall bathtub floor rather than a detachable groundsheet like our other tents. The bathtub floor is a rectangle 45 inches wide by 7.5 feet long (114cm x 2.3m). Plenty of space for two average people to stretch out plus space for gear at the ends of the floor.

    If you are particularly tall, you might try propping up the side guylines for even more headroom. Some couples prefer the additional width in a Triplex tent.
  • The bathtub floor has a Mesh Pocket. at both ends for storing small items like your flashlight, glasses, phone, etc. The pockets are about 8" x 8" (20 cm x 20 cm). Older tents can be retrofitted with stick-on Mesh Tent Pockets.
  • A separate groundsheet is Not required for this shelter. The floor material is reasonably durable, and all Cuben Fiber gear can be easily patched in the field with repair tape.  If you do prefer to use a groundsheet as a precaution, Flat Cuben Fiber Groundsheets are available.
  • There is screen between the bathtub floor and the walls at the ends of the tarp. An elastic cord keeps the bathtub elevated ensuring the screen slopes downwards away from the bathtub. Any condensation will run down the walls and out through the downward sloping screen, rather than onto the floor.
  • All of our tents do pretty well in the wind. The material can handle high wind loads. As long as your stakes stay in the ground (use rocks if available) your tent will stay standing. Cuben Fiber is not a particularly noisy fabric, however almost any tent will make a little noise in the wind. Ear plugs are not a bad idea for windy nights.

  • The Duplex Tarp with taped seams and sewn in linelocs weighs 9.5 ounces (269 grams)
  • The included guy lines and door clips weigh about 1.2 ounces (34 grams)
  • The sewn in Cuben Fiber bathtub floor and bug screen weighs 10.0 ounces (284 grams)
  • The included medium-plus 7" x 13" stuff sack adds .3 ounces (8 grams)
  • The total weight for the packed tent is 21.0 ounces (595 grams).
  • 8x Stakes are required but are not included. We have a variety of Ultralight Stakes to choose from.
  • These weights are as accurate as possible. Compare carefully! Many other manufacturers leave out seam sealing, lines, line locs, stuff sack, stakes, etc from their weights.


  • Our tents are made from Cuben Fiber material. Cuben Fiber has several advantages over other materials:
    • Cuben Fiber has a very high strength to weight ratio. The material can handle high wind force and does not tear easily.
    • Cuben Fiber is inherently waterproof. No DWR or coatings to worry about.
    • Cuben Fiber doesn't absorb any significant amount of water. No extra water weight to pack up.
    • Cuben Fiber is made from Dyneema threads which do not stretch. The tent stays taut all night. Nylon material by comparison can stretch and sag, especially if it gets wet.
    • The seams are stitched and then taped water tight. The tie outs have bonded reinforcements for high strength. No seam sealing necessary!
    • Tape sticks well to it. Any damage can easily be fixed in the field with our Cuben Fiber Repair Tape.
  • Cuben Fiber is semi-transparent. In bright sunlight you can see a fuzzy silhouette of a person sitting inside the tent. You cannot see any details and it has a suitable amount of privacy for changing clothes etc. In lower light (such as in the evening or at night) you cannot see through at all. We also have thicker, darker Cuben Fiber material available as an upgrade that you can choose.

    One nice thing about Cuben Fiber is you can also see the outlines of trees and your surroundings for a more connected outdoor experience.
  • This tent has fully enclosed .7 oz/sqyd (24 g/m²) insect screen. The holes in this screen are super tiny, even the smallest insects cannot get through. Our tent screen is about 30% lighter than comparable Noseeum screen with no noticeable decrease in durability.
  • The bathtub floor is made from 1.0 oz/sqyd Cuben Fiber. This material weight is more than twice as thick as the canopy material and is more resistant to abrasion and punctures. As with all Cuben Fiber it is easy to patch with tape.
  • Lineloc 3 adjusters are sewn to all tie outs. Bright yellow Dyneema Z-Line cord is cut for you and included. The yellow lines are very easy to see night or day, and Dyneema has very low stretch.
  • The expected life span of this shelter is at least one full 2500+ mile thru hike, or many years of casual use with some care.
  • All Zpacks gear has a one year warranty against defects in materials or workmanship. Returns or exchanges are welcome.

Material Choices:

.51 oz/sqyd Standard Cuben Fiber Fabric

The default material choice on this tent is .51 oz/sqyd Cuben Fiber. It has high tensile strength and can handle strong winds, storms, and all the typical conditions a tent will be in. This is the weight I used on all my long distance hikes, and I've never had a problem with it becoming damaged. If it ever were to get punctured or torn, I know that I can fix it easily in the field with Cuben Fiber Repair Tape. A piece of matching repair tape is included with the tent.

The floor material on our tents is always thicker more puncture and abrasion resistant 1.0 oz/sqyd Cuben Fiber regardless of which tarp material you pick.

.67 oz/sqyd Camo Cuben Fiber Fabric

This material has the same Dyneema thread count as standard .51 oz/sqyd, but with a slightly thicker laminate with a Camo pattern on it. The Camo print brings the fabric weight to .67 oz/sqyd.

It blends in to nature well. It is darker, less transparent and offers more privacy. Cuben Fiber has a bit of a sheen to it when it is new, but it dulls down significantly with some use.

This video by John Abela shows the Opacity and Color of Camo Cuben Fiber.

This material is more expensive. It adds around 1.5 ounces (45 grams) to the weight of a Duplex.

.74 oz/sqyd Spruce Green Cuben Fiber Material

This material has a higher Dyneema thread count which gives it a higher tear strength. The standard material is already difficult to tear, so in our opinion this weight is unnecessary. Some people like it for added peace of mind.

It is also a bit thicker and darker than the standard weight. It is less transparent and offers more privacy, but it is not as dark as camo.

It adds around 2.2 ounces (62 grams) to the weight of a Duplex.

"The Zpacks Duplex Tent has quickly become one of my all-time favorite backpacking tents."

"When making a major purchase like this, remember to consider the whole's not just about the product you are buying, but the company and people behind it. Zpacks scores on both accounts."
Steve B. Reviews the Duplex Tent
"I can say without question that I have not once felt bummed I spent so much on a shelter. This is the first time when I have absolutely known it was totally worth it."
John Abela's Duplex Tent Review
"This tent is huge. With a long sleeping bag, I never touched the ends of the tent or got the bag wet at all. At one point, we (three 6ft tall guys) all sat in there together playing cards and were comfortable. Setup took about two minutes each night."
BoredInTheSouth Reviews the Duplex Tent
"The weight to space ratio is undeniably fantastic."
Fellbound (UK) Reviews the Duplex Tent
"I can't comment yet on how the tent handles bad weather; however, it certainly feels sturdy. The ergonomics of the tent were pretty much perfect for us. My wife loved the tent and loved getting her own view, which certainly helps me when spending this amount of money! The four door system is very flexible and is a great solution. We really, really like this tent." -William C.
"Used the Duplex shelter in grand canyon last month, awesome shelter. The Duplex is substantially lighter than what I had before, but also with bug protection and a great groundsheet. I'm really happy with room, at six feet with big feet and using Neoair, I usually rub the foot of my bag on enclosed shelters, but not an issue at all with the Duplex." -Jon F.
"Just got your tent today. In typical Outer Banks fashion it was blowing 30 to 35 and raining, so I set it up just to check it out in some weather. Man that tent is awesome! Plenty of room and rock solid. I love the two doors and the vestibule space. Blown away by the craftsmanship. I can't wait to take it out on trip. Thank you man" -Bob S.
"Love the tent and sleeping bag. Took them out on the AT this weekend in Maryland. Wind was blowing 30mph Friday night which made my first time setting up in the field a challenge. Not to mention setting up on rock. It then rained to beat the band so my Duplex got a very good first workout and did well. Thanks again for the great products!" -Rich M.
"I wanted to let you know that the Duplex tent rocks and so far and I am very happy with my purchase. I got lucky, the first night out it rained all night and the following day. It has just the perfect amount of room for me and my dog with room for gear. I didn't think the floor space would be much bigger than the Twin, but boy does it feel bigger" -Josh P.
"I am back from my 6.5 day, 83 mile “Q” hike at the Torres del Paine in Patagonia. 5 of us hiked in and the 1st day it rained and blew like crazy. The other campers made interesting comments about my space ship and how they would be amazed if it stayed up. Well come the morning, after a very windy and rainy night, all was good with the tent - no issues other than it was noisy during the night. You had advised taking ear plugs which was great. Other tents had issues during the night so had a lot of visitors in the morning wanting to know more about the tent - they could not believe the weight and roominess in side. Awesome trip, bad ass hike and great equipment." -Tony L.
"The tent worked like a dream, even in high wind. Some challenges in staking the tent in river sand (I used large boulders ~15kg each and extra ties). The wind hitting the tent moved some of these boulders but the tent was fine! Nights were below freezing and quickly heated up when the sun came out. With the tent being well ventilated, a good sleeping bag is essential." -Peter J.
"I wanted you to know how happy we were with the Duplex tent you made for us for our JMT hike. Setting up camp and breaking down was SO easy with your tent! My wife and I would have the Duplex set up in about three minutes and would then sit and relax to enjoy the scenery. Getting ready to break camp in the morning was just as easy. We were ALWAYS done WAY before our friends." -Joe R.
"I believe the Duplex tent is the best all-purpose backpacking tent in the world." -Max Neale, (formerly) Outdoor Gear Lab Editor
"I have just returned from the JMT using your Duplex tent, sleeping bag, and accessories. We got rained on very hard, and all the gear proved itself to be very reliable - so wanted to say - Thanks!! It was a pleasure carrying the low weight and by that enjoying the view :)" -Neer Z.
"My Duplex tent is my absolute favorite possession. So much room for me and all my gear to stay dry and bug-free. Everyone comments on how small and lightweight my pack is and how spacious and nice my tent is." -Mark H.
"I had the Duplex tent out on the JMT for 20 days, 10 of which I got rained on. The Duplex worked out great, I wouldn’t of wanted any other tent out there. Feel free to post." -Ken K.
"I absolutely love, love, love my new Duplex shelter as a one person shelter. It stood up wonderfully in the all day all night rain we had for 36 hours. It stood up in cloudbursts with winds of probable 35 to 40 mph. It had enough space for me to dress, relax, "camp out", and enjoy. I hadn't realized it from your webpage info, but closing all four doors snugly really enhanced the solidness and takes advantage of its basic hexagon shape. Opening a door on each side, when the winds die down, lets you stay weatherproof and still see around. I couldn't be more pleased. I was torn about whether to order the standard weight cuben fiber or the heavier cuben fiber. I decided to follow your advice, and I'm completely glad I did. The heavier material would have added cost and weight with no benefit, as far as I am concerned." -Barry W.
"Here is my Duplex Tent on recent 12-day expedition to the Philmont Scout Ranch. Very wet last 5 days but I stayed dry and definitely mastered how to set it up in torrential rain. Your rain gear and tent made the wet portions of the trips so much better to deal with. Just love both pieces of gear!" -Rich M.
"I love my new Duplex tent. I've got 6 or 7 tents, and this is far superior to any of them." -Hugh A.
"The Duplex saved us during 3 very stormy nights including one with around 12 hours of continuous heavy rain. All the thru hikers we spoke with the next morning had pretty wet sleeping bags except for us! Nice design Joe." -David T.
"I just finished a JMT thru-hike with a 60L Arc Blast and a Duplex tent, and they both worked fantastically. I had high standards for the tent because of its high price, but I think it's phenomenal. Its had no problem with overnight sustained 30mph wind or overnight thunderstorms, and the tent design does a good job of preventing and managing condensation. Given its weight, it's amazing how few sacrifices the tent makes. Really great job, folks." -Austin L.
"I recently returned from completing the Wind River High route in Wyoming and I took along the Duplex tent. What an amazing tent! I was impressed with the quality and functionality of the tent as well as how easy it was to setup and takedown. For its size it is amazingly light and packs small. We had wind, rain, hail and everything in between, it performed better than expected in all conditions. I liked having two vestibules when the weather was bad, or the ability to keep them open when the weather was good. Thank you for the great gear!" -Brad S.
"I would like to thank you for the quality products you have produced for me. I purchased one of your sleeping bags and then a Duplex tent. I have used the bag and tent in the Sanoran Desert and recently on a section hike of the PCT in the Eastern Sierras. I always beat my hiking companion setting up my tent. I was concerned about wind with your tarp/tent style but even in very windy and rainy conditions, the tent kept me warm and dry." -Jon H.
"I am very pleased with the Duplex tent. It is light, very easy to put up, and very roomy. At 6’5” I do need space, and this has lots of it. Loads of room for me and all of my kit, sitting up or lying down. It is also a very clever design, and is well made. The Cuben fiber is a wonderful fabric. It seems robust, stays taut, and the tent copes well with wind (not yet tested in a full gale!). It’s fully waterproof. It does have a slight condensation issue, but then, all tents seem to. The way condensation runs down the inside and out through the mesh gap provided for it is very clever, and it works. And if two or more of the four doors are left open, condensation becomes minimal. I think it just has to be accepted that if the temperature inside any tent is noticeably higher than the outside, there will probably be condensation. A star buy, 10/10" -Jerry W.
"This summer I had the honor of breaking in the Duplex tent and solo sleeping bag at Philmont scout ranch. My crew and I covered 120 miles over the eleven days and your product made this experience priceless. Thank you for making best lightweight gear on the market." -Scott F.
"Your Duplex is the best backpacking tent that I have ever owned in almost 50 years of backpacking!! I LOVE IT! It has more space and is lighter than my previous “ultralight” tent - and is much easier to set up. I felt secure (and luxurious!) even (especially!) in heavy thunderstorms in Oregon and Washington. The Duplex was just a delight." -Joe W.
"I have been so happy with my Zpacks equipment. Incredibly light, durable for it's weight, and high performance in various conditions. The Duplex tent has been amazing on all my adventures from backpacking in the Rockies to pack rafting the Rio Chama to ski mountaineering Mt Rainier. I always get lots of questions and compliments about the Zpacks gear and always recommend it. People are amazed that something so light can be so functional." -Andy S.
"I absolutely LOVE the Duplex tent you made for me last year. It’s a great product and has stood up nicely here in Virginia." -Eric Y.
"Thank you so much for getting the Duplex tent to me within my ideal time-frame. I am so pleased with its performance after a three day trek In the Welsh mountains over Easter during which it stood up to a night of gale force winds and rain with no issues whatsoever. A great product." -Nigel P.
"By the way, last week I had to camp on a very exposed ridge in the San Gabriels with very fierce winds. The Duplex tent held up great despite - what seemed to me - taking a terrible beating. No damage done to tent as far as I’ve been able to tell. Fortunately I was able to find huge rocks for anchoring the tent stakes." -Joe W.
"I really did my research before my thru-hike / bought and returned many, many items just so that I could have ‘em in my hands and look at the stitching and study the design, etc. On the web, everyone claims to have a great product, but the shopper can’t know the truth until they hold it in their hands. I found Zpacks quality and design to be tops in the areas of bags, packs AND tents, that’s an impossible trifecta! My thru-hike confirmed it. Sorry, let me add Stuff sacks and Customer Support to that list! Thanks." -Fred L.
"Thanks again for your recommendations about snow camping! My Duplex Tent pitch wasn't perfect but it survived all the crazy wind and wasn't too cold at all! Glad I tried it out in the snow!" -Karen W.
"I'm on the AT and I love my tent. I've slept in it every night since I've gotten it and shown it off to a lot of people on trail." -Kasey M.
"I purchased a Duplex in Nov 2013 shortly after they became available, so I suspect I have one of the first run. Words cannot describe how much I like this tent…it is orders of magnitude more enjoyable than any other I have owned." -John H, (Comment received May 2015)
This BackpackingLight Thread has some sweet photos of the Duplex tent in action.
"My ski partner and I were pretty thrilled with how the Duplex performed in a range of winter conditions, and we were of course glad to have less weight on our backs. I've attached a couple shots of the Duplex tent from our trips.
Photo 1, Photo 2" -Serge G.
"I bought a Duplex tent last year and its by far the best shelter I have used. Been on a bunch of bike packing trips with it and have had nothing but great times ;-)" -Rick G.
"This letter is about my ranking the Zpacks Duplex as my favorite tent of all outdoor shelters I’ve used since 1958. I bought my Duplex from you a little over a year ago, and I’ve used it about 30 nights since then in Wyoming’s Cloud Peak Wilderness and in Montana’s Beartooths and Absarokas. I’ve used it in every month of the year!!! I’ve used it mostly for one person, but occasionally for two. I LOVE IT! I’ve never experienced a blizzard in the Duplex, but I’ve experienced hard, all day rain with wind gusts, lightening and all night wind. I’m amazed at the wonderful protection. Thanks for a wonderful invention." -Barry W.
"Last weekend we completed a presidential traverse; 3 out of 4 of us had your backpacks and tents. I slept in the tent above tree-line in a wet swampy spot in 35 to 40 mph winds and no problems. Lots of people commented on our packs and few knew of them but had never seen one. Very impressed with the packs and the tent. Very lightweight as advertised and seem quite rugged." -Curtis B.
"We have just completed our 515 mile hike across Washington on the PCT. Having now put our new Duplex tent and my Arc Blast pack through their paces, I wanted to send you some product feedback. First the Duplex tent--in a word, terrific! It was perfect for us and held up beautifully. It seemed so ephemeral when we first received it that it was hard to imagine it surviving the rigors of the trip, but we needn't have worried. With care and a post trip washing, it still looks new after more than 30 nights" -Heidi P.
"I just finished my PCT section hike (Campo --> Cascade Locks) using a Zpacks sleeping bag and Zpacks Duplex tent. Both were awesome and served me well on my hike. The Duplex was my favorite piece of gear!" -Jake P.
"I wanted to extend to you a huge thanks for your wonderful customer service and your amazing Duplex Tent! It held up for me in snow, rain, and wind, and was my sanctuary in mosquito country. Attached is a shot of it at my favorite campsite. I have recommended the tent to many people, and will continue to do so." -Julia H.
"My Duplex was pelted with golf ball sized hale with only a minor hole being punched into one of the corners. I was easily able to repair it in the morning with that Cuben Fiber tape (LOVE IT!!). I'll admit I originally thought it was because of the fragility of ultralight products until I took a walk around the lake I was camped at. I found a nylon tent with several unrepairable tears in the rainfly. I think my tent did amazingly well considering the conditions! I now have no such doubts on the durability of these products." -Tyler R.
"My wife and I have just returned from a backpacking trip in King's Canyon. We slept in the Zpacks Duplex tent every day and enjoyed our experience with it in every possible way! The tent takes minutes to pitch perfectly, has enough room for two people to sit up and also store small items in and around the mesh pockets. The bathtub floor indeed appears to be plenty strong for normal use with a little care taken when selecting the camp site to avoid very sharp stones and twigs. The mesh, while looking very fine and offering beautiful views of the surroundings, turned out to be very robust and will likely endure many years of normal use. We found the workmanship and the material quality unsurpassed and are looking forward to replacing many of our other backpacking items by those offered by Zpacks in the future." -Aliaksei C.
"My Zpacks Duplex tent was such a great purchase! I've camped in the worst thunderstorms imaginable with very high winds and rain and the tent kept me snug as a bug in a rug. The open/shut sides are a great feature because it gives cross ventilation when open and seals out extremely bad weather when closed ... plus gives additional protected out-of-tent space. And it takes about two minutes to put up. The tent is very well made, extremely lightweight and takes up very little space in my pack. It is something I will keep and use the rest of my life! Awesome purchase!" - Linda Bliss
"I took my Duplex tent to enjoy the last weekend of summer at Emerald Lake in the Cloud Peak Wilderness. I knew I'd be getting into some snow, since in rained in Sheridan Thursday afternoon. As always, the Duplex was great. I use it when I go solo, and I use my Triplex when I go with someone else." -Barry W.
"If you and your staff only knew how many times I sang your praises on the CDT this year, both to others and silently to myself. Such as when:
--Just barely off the summit of Mt. Taylor, hail slammed the tent like machine-gun fire with two solid inches still left on the ground the next morning, and the thermometer inside the tent read 19 degrees.
--My last night, ten miles north of Cubres Pass, at 12,300 feet on the exposed summit of Flat Mountain we had hours of sustained 30-, 40- and more mile-an-hour gusts. "Please hold, please hold," was my mantra. I was speaking to the seams, the fabric, the stakes and the carbon fiber tent pole (the second pole was my hiking pole)." -Barney 'Scout' M.
"Here is a Photo from Troop 858 on the Big Piney trail in MO. Duplex tent and 30 degree bag in left. Solplex tent, 40 degree bag and Arc Blast pack on the right. My Pack was down to about 26 lbs with food/fuel/water. MUCH lighter than on previous trips!! My knees are thanking me today. :) Gear worked great. Thanks for putting out great lightweight products that work as advertised." -Jamie B.
"I wanted to take a moment to thank you for your support while I was on the trail and for your Duplex tent. I completed my AT thru-hike on September 18th, 2015 and used your tent almost every night, except for a few town days. The Duplex performed as advertised; no water inside the tent and no condensation." -Robert H.
