What reviewers say
Owners mostly praise the weight and say the seams look solid. One Trailspace user reported dry contents after three straight days of rain, and others found they kept out water from a quick sink test. They are water-resistant, not waterproof: reviewers warn they won't save gear in a capsized canoe. A couple of users list the thin fabric's long-term durability as a concern, and some retailer reviews were collected through a promotion.
Good
- Nearly weightless
- Bright colors make sorting easy
- Slippery fabric slides in and out of packs
Not so good
- Not submersible
- Thin fabric needs some care
- Drawcord top isn't a seal
Who it's for
Backpackers who want an organized pack without adding weight. For river trips or boat decks, use a true roll-top dry bag.
