Perfect size for my 40-degree sleeping bag and the clothes I sleep in. Fits perfectly into the Arc Blast sideways. I love how all of the Zpack bags keep my Arc Blast organized and tight to my back, and I never have to worry about anything getting wet!!

Keep your gear dry and dust-free without adding any more weight than you have to. This size will fit multiple clothing items or an average-sized ultralight sleeping bag. It fits well horizontally in most backpacks.

  • 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.

  • Imported.

Held up well for almost ten years.

Giving this four stars because I got 11 years of use out of it as a stuff sack for my 20 F bag. I would, however, prefer this same stuff sack without the velcro. I was afraid that the hooks might cause abrasion to my sleeping bag, so I would roll the rough side of the velcro (the hooks) under as I stuffed my bag inside. As I did this, the hooks would catch onto the dyneema and tear away small strands. Eventually, enough dyneema was torn away that the stuff sack failed. Is there a velcro-free alternative that I can just roll and buckle?

Perfect for a Quilt

Zpacks Medium Plus Dry bag is the perfect fit for my 20 degree UGQ quilt (84"x55") and my spare clothes in the bottom of my Zpacks Arc Air pack. I've used the small dry bag for my electronics for a while and the quality, performance, and weight convinced me to upgrade to the medium plus for my quilt. Weighs in at .6oz.

Still in Review

So far, so good. I have had zero issues, thus far. I bought and use the bar for the sole purpose of storing my Western Mountaineering Versalite 10 degree bag, in redundancy for water proof while in my backpack. Just as I hoped it fits perfect in the bag! Wish I had never spent money on water proof compression sacks, but those the silly mistakes we can make juts getting into backpacking.
