  • Familiarity: I've used it once or twice and have initial impressions

Bought a couple of these for a trip to the narrows. They're great compression sacks, but not convinced they are 100% waterproof. My husband and I both used these for our sleeping bags and on day 2 of the trip submerged the bottom of our packs crossing chest height water. The bottom of our packs got soaked. My bag was still dry, but my husband's sleeping bag was definitely wet in spots.

Did the trick

I needed a compression sac to keep my sleeping bag dry on my overnight hike in the Narrows, this did the trick and actually compressed my bag more than the original compression sac it came with. The entire bag took a dunk and kept the sleeping bag dry, even though the pack stayed wet the remainder of the hike.
