ZPacks™ 40, 30, 20 and 10 Degree 900 Fill Power Down Sleeping Bags

Description:

Our sleeping bags combine the best aspects of a down quilt and a down sleeping bag at an unbeatable weight. The bag opens up underneath you like a blanket for easy temperature control when it is warm out, and a 3/4 length zipper and neck elastic allow you to bundle up when the temperature turns cold.

Available in 40, 30, 20 and 10 degree Fahrenheit temperature ratings (5C, -1C, -7C, and -12C), in a plethora of sizes. Each bag is custom built to your specifications.

The bags are now made with the lightest weight ripstop nylon available, .75 oz/sqyd Pertex GL for both the liner and shell! As usual they are made with the lightest possible 900 fill power down and Cuben Fiber baffles.

Girth:  Shoulders / Hips / Feet
Regular Width:  56" / 56" / 30"  (142 cm / 142 cm / 76 cm)
Wide Width: 61" / 61" / 35"  (155 cm / 155 cm / 89 cm)
Extra-Wide Width: 66" / 63" / 40" (167 cm / 160 cm / 101 cm) New Feb 2014!

The dimensions are measured with the bag opened up, stretched tight, from one edge to the other. If you already have a bag to compare, measure the same way.

How to measure yourself for Girth: Measure around the thickest part of your chest including your arms. Add at least 6-8" or more for wiggle room. For example, I measure about 48" around my chest and arms and the 56" regular bag is a snug but comfortable fit on me. Our regular girth bag runs slim compared to others.

Length:
A Medium 5' 9" bag should be long enough to cinch snugly around the neck of a person who is Up To 5' 9" (1.75m) tall. We recommend sizing up one length so that you have extra length to pull up around your ears when it gets cold.

Lengths are available to fit from Extra Short 5' 0" (1.52 meters) up to Extra Long 6' 5" (1.95 meters). Even longer sizes available on request.

See the chart below for details on most of the sizes.

Materials:
Constructed of the lightest materials available -
  • Outer Shell Material: Green .75 oz/sqyd (25.4 g/m2) Pertex GL Ripstop Nylon with durable water repellant.
  • Inner Liner Material: Black .75 oz/sqyd (25.4 g/m2) Pertex GL Ripstop Nylon with durable water repellant.
  • Baffle Material: .34 oz/sqyd Cuben Fiber
  • Fill Material: 900 Fill Power Premium Goose Down
Features:

  • Tightly spaced continuous baffles every 5 inches help keep the down evenly distributed. For the most warmth fluff up the down each night by shaking the bag before use.

    There are no "sewn through" cold spots, including in the foot area. The only cold spot is the zipper, which is positioned on the bottom underneath you.
     
  • Each baffle is overstuffed with 30% more 900 Fill Power Premium Goose Down than is necessary for maximum loft to account for any future down compression. Down bags can last for decades with care!

    Store loose (hanging in a closet for example) when not in use. Each bag has a hang loop at the foot.
     
  • Black .75 oz/sqyd Pertex GL on the inside for quick drying.  Green .75 oz/sqyd Pertex GL on the outer shell. Both the liner and the shell are treated with durable water repellant to resist rain spray and body moisture.

    The shell material is reasonably durable for normal use, and it can also be repaired easily with matching Pertex GL Repair Tape.
     
  • 3/4 Length Zipper extends to your calves. The zipper is positioned on the bottom of the bag giving it two advantages:
    1. The bag can easily be opened up for venting in "quilt mode". Most of the time you probably won't even use the zipper.
       
    2. Since the zipper is underneath you no draft tube is necessary- that means less weight and much less chance of a frustrating zipper snag.  Getting in and out is as easy as turning the zipper to the side, or just slide in or out the top of the bag.
    3. A draft tube is available as an option if you want one (below).

    You can also choose to leave off the zipper entirely. The zipper accounts for just .6 ounces (17 grams) of the bag's weight.
     

  • A clip at the top of the zipper keeps the zipper securely closed. Or use the clip alone with the zipper opened for venting.
     
  • An Elastic cord can be cinched tight around your neck to keep out drafts. Size up a length if you want extra room to wrap the quilt around your ears or tuck your head in.

    This bag does not have a hood- wear a warm hat, or a goose down hood instead!
     
  • A Cuben Fiber Roll Top Bag is included, and adds about .9 ounces (25.5 grams) to the listed weight.

    40F and small 30F bags ship in a Slim dry bag which is 5.5" x 12" (13 cm x 31 cm)

    Larger 30F bags and all 20F bags ship in a Medium dry bag which is 6" x 12" (15 cm x 30.5 cm)

    All 10F bags ship in a Medium-Plus dry bag which is 7" x 15" (18 cm x 38 cm)

    The dry bags are a comfortable fit and can be compressed smaller by squishing the contents and rolling the top down more.
     
  • All ZPacks gear has a one year warranty against defects in materials or workmanship. Returns or exchanges are welcome.
     
  • For more info check out the Sleeping Bag FAQs.

Washing Instructions:
Hand wash with warm water in a bathtub or bucket. Do not use soap unless it is made specifically for down. Normal soap can strip down of its natural oils. Typically warm water alone is sufficient. Do not machine wash- the twisting motion of a washing machine may cause tears. Line dry, or tumble dry on low heat. Store loose (hanging) when not in use!

ZPacks Sleeping Bag Review

"Just a little update for you. After 2 years of hard use using your quilt in floorless Shelters and bivy sacks, that thing is still going strong and has a ton of loft left in it. I love this quilt"

Matt Alley reports on his
10F Sleeping Bag
--------------------------------------------------
"I just returned from my thru-hike of the John Muir Trail. Your 30 degree quilt performed wonderfully. I was plenty warm most nights, although a little concerned at first. It got into the low 30's a few nights and I'd say the average low temp was around 38 - 40. The 30 degree rating is definitely an accurate rating especially when compared to bags or quilts of the same rating. And, as I'm sure you know, some manufacturers are more honest than others. I'd definitely take this quilt with me again in temperatures estimated to be in the 30's."         --Tyler F. from CA
--------------------------------------------------
"My constantly-cold wife has been using your 20 degree quilt since January 2012, in temps down to 25 degrees, and hasn't been cold a single night. She loves it!" --Austin from WA
--------------------------------------------------
"My 19 ounce, 20 degree bag that I bought from you gave me an edge when it came to weight and pack volume.  We were forced on many occasions to sleep out in some rather wet dewy conditions, and while I frequently woke up with a healthy layer of moisture on my bag and gear, the dry sacks never failed me and the sleeping bag always stayed warm.  It also dried out super quick.  You must already know how effective your products are in the field, but regardless I wanted you to know what a difference they made in my backcountry experience."
--Timothy W.
--------------------------------------------------
"Just got back from a two week trip in the Southern Rockies and had all kinds of weather.  Have to say that your sleeping bags worked fabulously and far exceeded our expectations.  Thank you for making such great (and light) gear." --Rob H.
--------------------------------------------------
"Just wanted to let you know that my bag performed superbly on my Cascades trip. I was super snug and actually preferred not having a hood if the truth be known. We climbed Shuksan via the Fischer's Chimneys and Southeast Ridge and I can honestly say I needed some good sleep (it was tough!) so I really really appreciated being warm and my big pack being lighter. Thanks again for making this one happen for me!"
--Viki T.
--------------------------------------------------
"I just wanted to let you know what a superior product your company makes. I just finished a hike of the arctic circle trail in Greenland and you bag performed flawlessly. I hardly noticed it in my pack and it was warm. The ability to use as a quilt kept me ventilated when I got too warm. I was gone for about a month and slept in your bag in ranges from the polar ice cap out to the coast. After that, I did trips to Iceland, the mountains around my house, and everywhere in between. It was perfect. I currently have the 10 degree wide, long bag (it is warmer then 10 degree in my opinion). There are very few things I would change about it. I can't say that about most gear. I will be ordering a new model in the near future for myself and my wife."
--Davy H.
--------------------------------------------------
" I successfully completed a NOBO PCT hike, starting May 19th and ending October 29th amidst the glorious snow. I used your 30* long / wide quilt and stuff sack pillow from start to finish and couldn't be more pleased with the performance!" --Seth B.
--------------------------------------------------
"Camped in the back yard last night as it hovered around 10 degrees. Wanted to give the new 10F bag a try. 40 mph wind gusts had the tent rocking a bit. I had to remove layers to dial in the warmth and the temperature rating was for me just right and then some. So in the end I have now saved around 1.5 lbs off my old sleeping system!" --Chris B.
--------------------------------------------------
The bag that we originally got was a little on the cold side for me (not the bags fault- as I get older I find that I just sleep colder). You guys took the bag back and sold me a warmer one for just a little more. I was extremely impressed with your level of service and the quality of the replacement bag. I've taken it out several times and have slept very comfortably in it. You guys are fantastic and make great stuff! --Sincerely, Kemper S.
--------------------------------------------------
My new Duplex tent and 10 degree bag were awesome this past weekend in Michigan. It got down to 7 degrees and I was the only one of 6 who didn't complain about being cold. Thanks! --Kevin R.
--------------------------------------------------
"I can't tell you how happy I was to get my new 10F sleeping bag! I've already used it on two short trips and it has exceeded all my expectations. From years of working at a high end outdoor retail store I can say with confidence that this bag blows every big name brand out of the water, at a reasonable price too." --Eli B.
--------------------------------------------------
"I just wanted to let you know that I returned from my JMT hike on August 11. I had lots of weather for those two weeks. My 20F sleeping bag kept me warm and dry! I was so thankful for this bag. Thank you so much for working with me!" -Diana H.
--------------------------------------------------
"I have to repeat what I tell everyone: your sleeping bags and other products, and your service, is the best in the industry. I’ve been using my new Solo bag all summer and still don’t believe how comfortable it is for sleeping and how feather light it is for carrying. Thank you for delivering a major quality of life improvement on the trail!" -Peter N.
--------------------------------------------------
Bobcat completed the triple crown (AT, PCT, CDT) in September 2014. "My ZPacks sleeping bags have over 6,000 miles on them and they're still going strong. This photo was taken on Texas Pass above Cirque of the Towers in the Wind River Range of Wyoming." -Bobcat

Zipper Options:


Option 1) By default the sleeping bag will have a 3/4 length zipper on the bottom. The zipper accounts for about .6 ounces (17 grams) of the bag weight. $0

Option 2) A full length two-way zipper to the last baffle. This will be a larger #5 zipper, which will add about 1.2 ounces to the bag weight. It can open from the neck, or from the foot for venting. Add $10.

Option 3) Adjustable Straps. Instead of a zipper, 2 evenly spaced sets of grosgrain straps are added to secure the bottom of the bag. The neck of the bag also has a clip. This is not as convenient or as tight a closure as a zipper but it is a little lighter and the straps can be cut off if you just want a straight quilt with no closure. You can clip the straps beneath your body, or you can wrap them around a sleeping pad as shown. You are welcome to add this in addition to a zipper, just add both to your cart. $5

Option 4) Zipper to join two Sleeping Bags together. This option adds a full length #5 zipper extended to the toe of the bag, AND a draft tube. This should be ordered along with a second sleeping bag that also has this zipper option. The two bags do not need to be the same girth or length, they just need to be built with the same length #5 zipper to join up. When the bags are zipped together the draft tubes will be positioned such that both are covering the zipper at the top center. When used solo the zipper and draft tube will be in the standard bottom configuration underneath you. This adds about 1.2 ounces for the larger zipper and 1.2 ounces for the draft tube to each bag (+2.4 ounces each). $35  Photo 1  Photo 2

Zipper

Draft Tube:

The zipper is the only "cold spot" on this bag. Normally the zipper would be positioned underneath you where cold air won't get through. If you roll around alot and aren't comfortable keeping the zipper below you a draft tube can be added to cover the zipper. The draft tube has a stiffener to help keep the zipper from snagging on it. It adds 1.2 ounces (34 grams) of weight.

Draft Tube - 1.2 oz (34 grams) - $20

900 Fill Power Water Resistant Down:

Water resistant down is just normal down that is washed with a water resistant treatment by the factory. In theory this treatment makes the down take longer to wet out, and may retain a little bit less water after being soaked, however real world results are hard to observe. The down still wets out after a while and you still need to be careful to keep your bag dry. I personally think that the benefits are very minor. We have also noticed that the treated down can be more clingy and can take more work to break apart clumps and fluff the bag up, which could result in cold spots if the bag isn't fluffed well.

It is for this reason that we have decided to streamline our production and discontinue WR down as a standard option as of November 2014.


Down Overfill:

The amount of down in each sleeping bag is explained Here. The sleeping bags are overfilled 30% based on the calculated amount of 900 fill power down required to fill the volume.

We are no longer doing in between temperature ratings or bag lengths as it makes construction and exchanges difficult. If you sleep cold at night consider going down to the next lowest temperature rating. Exchanges are welcome on any of the standard sizes and temperature ratings!
