This sack ditches the doodads in favor of simplicity.
Air valves make a compression sack bulky and hard to handle, so the geniuses at Outdoor Research came up with a better way. Instead of valves, the AirPurge Dry Compression Sack uses a section of air-permeable fabric that allows air to evacuate from the inside out without letting water from the outside in. All you have to do is fill this compression sack with gear, close it, and cinch it down until all the air escapes from inside. Your gear takes on a nice, compact form and it's protected from rain at camp or a torrential downpour on the trail.
- Nylon shell is durable and lightweight
- Air-permeable nylon band at the bottom of the pack allows air to escape from inside so you can get full compression, but it doesn't allow water from the outside to sneak in
- Full seam-taping ensures that water can't leak in where two materials come together
- Top closure rolls down and clips together forming a waterproof seal that's secure and dead simple to achieve
- Four compression sacks help you fully evacuate air from inside this sack and get the compression sack down to its most compact form
- Other features include a durable buckle closure, external daisy chain attachment point, and a webbing handle on the bottom

Compression Strap Tore in the Field
- Familiarity: I've used it once or twice and have initial impressions
Was looking to save some room in my pack by compressing my sleeping bag, but when I went to sinch the straps, the bag tore at the seams. Will stick with sea-to-summit here on out. I should have never strayed. I was a little suspect of the durability of the product before use...light weight but cheap! Mouth was plenty wide for a down sleeping bag.
I love technology like this.
- Familiarity: I've put it through the wringer
Air goes out and water stays out. Awesome stuff. I've got a slew of different sizes used to stuff sleeping bags and some clothes just in case. Take your time working the compression straps and it works perfectly. Act a fool and pull on them all crazy without doing a nice job and I can see why some could become frustrate. Do it right the first time. Didn't the teacher with the paste say that?
Tough to Stuff the L and XL
- Familiarity: I've put it through the wringer
We brought these on a trip this spring and the small opening at the top of the stuff sack makes it very difficult to stuff larger items in there such as a tent fly, even though we had the xl size. Compared to my Sea To Summit eVent sack this gave us trouble every time we had to use it. Definitely waterproof and durable just wish the opening at the top was wider and the bag itself . It did work out awesome in the S size for extra layers just would not try to get an XL again and put big items like a sleeping bag in it.
Great stuff sack performance
- Familiarity: I've put it through the wringer
I have used this in various ways since i bought it a little over a month ago it has been in a kayak,backpack, trunk of a car and roof box. The material seems thin and easily ripable but it hasn't yet and if it was going to it would have with my abuse. really light great compression whats not to love. I have both this and the Sea to Summit e-vent and both are good however the Sea to Summit is easier to use in the beginning with compression system around the outside however I found that I haven't touched it in over a month
I never used the air tight compression sacks, I always used just a "how tight can you pull the straps?" sack. I borrowed a buddies Sea to Summit sack and I was sold on that style, when I went to purchase it, it wasnt available in the size i needed for my 0degree mummy. Purchased the OR sack instead and I couldn't be happier. from now on, its the only way to pack my sleeping bags. you will be amazed at the compression ability of these sacks. They squeeze out all the air, then you roll and buckle the top to basically vacuum seal your sleeping bag. it seriously cut my stuff sack size by at least 25% over my old slumber jack stuff sack.
