Got a hole in it on the very first use.
Should've been a bit tougher. A waterproof bag aint waterproof if it gets any hole in it at all. So they should be built very robust. These aren't.

[This review was collected as part of a promotion.] Very lightweight. Using as a pack to fit on a small rear bike rack. Pretty impressed with what fits in here. Is perfect for the back of an XS bike for bike packing.

Practically weightless. I used it floating on the Russian river in an inner tube and everything stayed perfectly dry. Highly recommend!

Took this on a river trip a couple weeks ago. It tore on the second day. Not at all durable. Do not buy. Very disappointing from an expensive brand like Osprey.

[This review was collected as part of a promotion.] I backpack in rivers (ex: Escalante river UT) and do a lot of spring river crossings (ex: CDT, CO peak climbing). I carry my Garmin messager and phone in a side pocket on waist belt. It is only a matter of time before you fall in. This dry bag fits in side pocket, keeps critical electronics dry and allows quick access for navigation on Gaia or photos. Perfect size weight and price.
