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 .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.

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

Volume: 340 cubic inches / 5.6 Liters

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.

ZPacks dry bags

I purchased 3 of the ZPacks bags for my upcoming JMT hike. The bags are incredibly light and strong. Excellent service.

Perfect size

Perfect bag for extra clothes or a quilt or sleeping bag.

Great quality!

Zpacks products are superior in quality and value. We tried a dry bag from a lesser known brand (known for personalization) and it doesn't have the security of a velcro closure across the roll top, like the Zpacks bag does.

Medium dry bag

I used the bag to stuff my REI 30 degree quilt into, because the stuff sack REI provides is about the size of a 1 liter Nalgene bottle. I have not had an opportunity to try it out while backpacking yet, but so far all look to be what I expected with the purchase.

Leicht und stabil

Das Teil ist unglaublich klein im Packmass, zudem extrem leicht und auch super Stabil, kenne nichts vergleichbares.
