ZPacks™ 40, 30, and 20 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 a nearly unbeatable weight. The bags open up wide on the bottom 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, or 20 degree Fahrenheit temperature ratings (5*C, -1*C, or -7*C), in a plethora of sizes. Each bag is custom built to your specifications.

Quick Specifications:

40 Degrees (5* C) - Medium Length, Regular Width - 11.6 ounces (329 grams)  $305

30 Degrees (-1* C) - Medium Length, Regular Width - 13.5 ounces (383 grams)  $315

20 Degrees (-7* C) - Medium Length, Regular Width - 16.8 ounces (476 grams)  (shown in the pictures)  $340

See chart below for details on all the sizes.

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.
     
  • 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.
     
  • Silky soft Black .64 oz/sqyd SevenD ripstop nylon on the inside for quick drying. More durable 1 oz/sqyd Intrepid nylon on the outside is treated with DWR for water repellency.
     
  • 3/4 Length Zipper. 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".
       
    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.

     Other zipper options are available below.
     

  • Elastic neck cord can be cinched tight around your neck to keep out drafts. This bag does not have a hood- wear a warm hat, or a goose down hood instead!
     
  • Pretty much any size or temperature rating is available as a custom order (just ask!).

    Our regular girth bags run a little slim to reduce weight and increase warmth (less air to heat up). At 5' 9" tall and 155lbs the medium length, regular girth bag fits me comfortably. You can also choose a wide bag which adds 6" to the chest circumference for more wiggle room.

    The length of the bags will fit a person who is up to the indicated height. For example a medium length bag will fit a person up to 5' 10" (1.78 meters) tall.
     
  • All ZPacks gear has a one year warranty against defects in materials or workmanship. Returns or exchanges are welcome.

Constructed of the lightest materials available:
Outer Shell Material: Green .95 oz/sqyd Pertex Quantum Ripstop Nylon
Inner Liner Material: Black .64 oz/sqyd SevenD Ripstop Nylon
Baffle Material: .34 oz/sqyd Cuben Fiber
Fill Material: 900 Fill Power Premium Goose Down

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 tear the internal baffles. Line dry, or tumble dry on warm heat.

Store loose (hanging) when not in use!

"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."

Zipper Options:

Option 1) By default the sleeping bag will have a 3/4 length zipper on the bottom. The normal zipper has a pull tab on the inside and the outside. $0

Option 2) Elastic Straps. Instead of a zipper, 3 evenly spaced sets of loops can be added to secure the bottom with elastic straps. This is not as convenient or as tight a closure as a zipper but it is a little lighter and the straps can be taken off entirely. 3 detachable elastic straps and clips are included and they weigh .2 oz (6 grams) compared to .6 ounces (17 grams) for a zipper. $0

Option 3) Sewn Up. The bag can be sewn all the way up rather than have a closure system. You would get in and out through the top. If you sew up the bag you lose the versatility of opening it up when it is warm out, but it drops about .6 ounces (17 grams) of zipper weight. $0

Option 4) Side zipper with draft tube. Rather than have the zipper on the bottom of the bag it can be moved to the side (like a normal sleeping bag). A side zipper needs a draft tube sewn over the zipper to prevent cold air from getting through. This adds about .8 oz (22 grams) of weight and increases your chances of snagging the zipper on the draft tube, but it is more convenient to zip. $20

Option 5) Separating side zipper to join two bags. This is just like option 4, except with a 56" separating zipper to zip two sleeping bags together. The separating zippers only have a pull tab on the outside, so you need to reach outside the bag to unzip it (a minor inconvenience). Any two bags can be zipped together, for example a long and a short as shown above. This option includes draft tubes over the zippers which adds about .8 oz (22 grams) to each bag. One of the zippers will be at the top center and the other at the bottom center when zipped together. $20 each.

Zipper

Down Overfill:

The amount of down in each sleeping bag is explained Here. The sleeping bags are already overfilled 30% based on the calculated amount of 900 fill power down required to fill the volume. If you would like to add extra down to help boost the temperature rating you can add an extra ounce or more here. Any overfull will be distributed proportionally throughout the bag.

1 Ounce Overfill Down - $12

Shipping is just $3.95 in the U.S., $9.95 Internationally and up.
