I love this dry bag. I needed one for my handlebar harness while bikepacking. It’s perfect. I can fit my duplex, tent poles, stakes, sleeping pad and pillow in it. Zpacks isn’t just for backpacking!!!

Stop the elements from soaking your gear. The ‘Big’ size dry bag has extra space for bulky clothes or a larger sleeping bag. The girth will fit horizontally in deeper packs.

  • 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 our dry 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.

Superlight & Waterproof

Does everything it needs to do while being superlight. Plus, the semi-transparent nature of the fabric helps identify gear in your pack

Dry bag

Functioned as advertised. I like the velcro. I used them for anything in my pack I needed to stay dry due to river crossings and rain.

Perfect bag

I bought a few dyneema bags from Zpacks, including this big dry bag. I put all my food in it for 5 days. I had a smaller bag for clothes. These bags are the lightest out there, and have excellent closure at the top. Highly recommended.
