I have multiple sizes but plan to get them all. I've had many compression sacks and these are the strongest and lightest! Gets used 100+ days a year in my work pack as a Wilderness Ranger in the WA Cascades. Fast shipping as well. Highly recommended!

I absolutely LOVE this thing! And Luke was spot on when I asked his recommendation for sizing for my sleeping bag! I waited a while to review it until I had a chance to use it (backpacking got put on hold for a bit), and it's by far one of the best purchases I've made for my pack! Super easy to compress everything down - more so than the stuff sacks things come with! And the construction is really solid! And there's nothing quite like the piece of mind that comes from knowing your down sleeping bag/quilt(s) are in a water proof bag! Seriously, if you're on the fence, just buy it! you won't regret it!

OMG this bag is IT! I’ve tried different Dyneema bags to keep my super fluffy 15 degree down quilt in, but with the narrow shape & cinch-down straps, this blows them all out of the water. Fits perfectly in the bottom of my pack. It arrived quickly & the company was really great to work with.

Perfect for ultralight backpacking. I bought them for my top quilt and under quilt. Both compress beautifully. Well made sacks!
