Lead Time Ships in 2 weeks

Trek through damp forests with confidence and dry gear. This is a good size for multiple clothing items, a tent, or a down quilt. This size fits well horizontally in most smaller backpacks.

Need a different size?  Check out the rest of our Dry Bag collection.

  • 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 .51 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.

Flat Dimensions: 9.75" wide x 19" tall (25 cm x 48 cm)

Full Dimensions: roughly 6" diameter by 12" tall (15 cm x 30.5 cm)

1.0 oz/sqyd Dyneema Composite Fabric

Dyneema Composite Fabric is composed of high strength Dyneema fiber laminated inside a polyester membrane. It is inherently waterproof and does not require any coatings or DWR treatment. Dyneema Composite Fabric has very high tensile strength for its weight and does not stretch.

1 oz/sqyd Dyneema Composite Fabric has a thicker membrane giving it more abrasion resistance. We use it for dry bags and tent floors.

Tensile Strength:
 104 lb/in (911 N/5cm)

Puncture Strength: 3.5 lb (15.5 N)

Water Resistance: 20,000 mmH₂O

Made in the USA.

Zpack gear

I’ve used Zpacks drybags since 2014 and have been pleased with their performance. I’ve driven down to the shop and met Joe personally and looked at the gear produced there. I have purchased two arcblast packs and with over 2k miles on one had some buckles broken on one which Zpacks repaired with no charge. I’v been using the camo duplex tent and it’s the best tent I’ve ever used. I’ve been backpacking since 1964 and have carried packs from blanket rolls to before frame packs to Boy Scout external frames to Keltys to most modern packs. I think Zpacks gear is great and the customer service is too. A big fan of this gear.

Return customer

I really like supporting small companies and especially if they serve a niche market. My only issue is was that the order took over 2weeks to deliver and I ended up having to go to REI to buy a commercial brand for my trip. I will still keep the 4 bags that I ordered regardless because they are great.
