Keep your gear dry when the weather is wet! The slim size dry bag will fit well in smaller backpacks. It is a good size for lightweight clothes, miscellaneous loose items, or a summer quilt. It is also useful to store flat items like a book, maps, or documents in an average depth backpack.

  • Constructed from black 1.0 oz/sqyd Dyneema® Composite Fabric which is inherently waterproof and abrasion resistant. By comparison our regular Stuff Sacks are made from thinner .55 oz/sqyd material.

  • Fully taped seams. Our dry bags will keep water out in typical backpacking conditions where the bag is not submerged.

  • The top of the bags seal with stiff velcro to make closing and rolling the top easy! Air can escape from the rolled velcro, allowing these to squish flatter in your backpack as more gear is piled on top.

  • Also check out our Zip Pouches for water and abrasion protection for your smaller items like your wallet, camera, phone, passport, glasses, etc.

  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.

  • Made in the USA.

This dry bad sits perfectly in my pack's bottle pocket which is prefect for hikes in Lapland where you don't need to carry water. I use it for my tent's outer layer and for extra food.

Slim Dry Bag

Well made with good materials. Originally, I was skeptical about a stuff sack or dry bag not having a round bottom. No longer am I skeptical. It packs well both in terms of holding my gear and sliding in and out of my backpack. I haven’t submerged the dry dry bag, and don’t plan to, but I did fill it with air and then closed the top and rolled it down 3 or 4 turns and clipped the top in the usual manner. Then I squeezed the bag to see if I could get air out of it. I could, but I had to put a good deal of pressure on it. My conclusion is that for all intents and purposes, this is going to keep my down quilt dry no matter what conditions I’m experiencing short of submersion for more than a few minutes.

Great dry bag

It’s the perfect size to fit a 40 degree mummy bag. It fits in the Arc Blast nice and snug! Well made and is tough as nails! It’s nice to not have to worry about the sleeping bag if I get water in the pack.

Great way to expand your pack

I have an older Arc Blast as I use to spend a lot of time hiking and sleeping on the ground, having made the move to a hammock and all that goes with it, I was left with nowhere for my Underquilt and looking at adding another pack, but this slim dry bag is the perfect size for my 20 degree full length under quilt and allows me to keep using my favorite pack while I experiment with the hammock and truly identify my long range needs. As always top notch quality you know and depend on from Zpacks.
