Sea to Summit eVent® Compression Dry Sack



A completely new concept in compression dry bags - there is no valve. This innovation uses an air-permeable base made of eVent waterproof fabric, which allows air to be pushed out of the sack, but won't allow water to get back in.

Great product yet to use it out in the mountains but found the medium a good size to compress my first Ascent XV down jacket together with my Mountain hardware Down Absolute Zero pants to a nice compact minimal size allowing it to keep dry for those cold nights out at higher altitude or the summit attempt...

I used the large sack for compressing my MH Lamina 0 sleeping bag for my Rainier climb, and it worked exceptionally well. Easy to use, and amazing as to how small it compressed my sleeping bag. Exceeded my expectations, which isn't easy to do! smile Mac

Great bag that allows me to get my down bag into a much smaller package once the air vents out the eVent material. This kept my bag dry in the nasty rain and 40 MPH winds on Mt. Rainier. I was really glad to have a dry bag when I opened my pack to find the bottom pooled with water.

I have two of these dry sacks in medium, and they are great! It's all about the eVent fabric - I've brought these with me kayaking on the Mekong River, horse-riding in Mongolia, whitewater rafting on the Franklin, and it kept my things dry. I never go on an adventure trip without these. Pros: you can stuff a lot into one sack, and they even allow damp clothes to dry Cons: none
