Rated 5 out of 5 by from Keeps your stuff dry and small Kept my sleeping bag and clothes dry when backpacking in a downpour. Nice and light. The 10L is a good size for very compressible down sleeping bags like the REI igneo, and the 15L is a good size for bulkier synthetic bags. I've found the best method to compress these is to put the more durable looking black (opening) end on the ground and sit on the orange end (the end with the handle). Then pull up on each strap in succession a few times until you've compressed the bag down to your desired size. It's so nice and compact afterwards that the hardest part is resisting the urge to toss it around like a football.

Rated 4 out of 5 by from Worth the money I have three of these bags. My wife and I use this for down sleeping bags and my down underquilt (hammock camping) when we go out. The bag works very well, and its is made out of durable material. I have never had any problems with water seepage My only drawback for the bag is the buckles on the compression straps. The straps are plenty strong, but the buckles where they are attached to the bag are lacking. I had a buckle split on me after a few trips, but this was only one of four buckles per bag out of three bags. Also, the buckle didn't change the waterproofness, just the compression. I finished my trip, went to REI and the exchanged it with no problem.

Rated 5 out of 5 by from This sack can survive a WATERFALL! I bought this compression sack for my down sleeping bag because I needed to keep it dry. This does the job better than anything else in it's class. Recently, I was setting up camp on top of a large waterfall. I accidentally kicked this sack, packed with my brand new sleeping bag into the river and watched horrified as it went tumbling off the waterfall. It took at least 15 minutes to get to the bottom to retrieve it, and it was stuck directly under the fall the whole time! To my great surprise, (and relief) my sleeping bag emerged from the sack BONE DRY. This product is well worth your money!

Rated 5 out of 5 by from Get One This is my third Sea To Summit eVent and my first STS compression sack. The eVent bags are so easy to use- just close it up and kneel on the bag and out goes all the air. I needed a good compression sack to compress down my sleeping bag and so got the eVent Compression sack. The sack's material is strong, waterproof and durable and the compression straps are really solid. I know it'll keep my sleeping bag nice and dry and it compresses down so well my sleeping bag takes up only a little room. I have a Kelty Light Year XP (women's regular) sleeping bag and the large eVent Compression sack is the perfect size.

Rated 5 out of 5 by from Great for all conditions! I have used this bag extensively over the past few years, and it has been a life-saver time and time again. It has been used from the hot and humid coast of Kenya, where breathability is essential to prevent clothes and other gear from growing mold when being stored, to the top of Mt. Kenya, where a burst water bladder in my pack would have meant sleeping in wet clothes and sleeping bag at 15,000 feet above sea level. This bag has always kept my gear dry, and in spite of hard use for 3 years is only just beginning to show wear and tear. I will definitely buy another one when the time comes.

Rated 4 out of 5 by from Holds a bulky REI sleeping bag I recently bought an REI Polar Pod extra long sleeping bag for car and kayak camping that requires a large eVent compression dry sack to allow room for enough folds in the top to seal. This dry sack's compression straps make it possible to compress a bag down a reasonable amount, but users of kayaks with smaller hatch covers may want a more compact sleeping bag/compression dry sack combination. All it would take is spending a lot more on a sleeping bag than I needed to. Overall, the compression dry sack does its job, and I'm satisfied that I'll arrive at a campsite with my sleeping bag dry and ready to crawl into.

Rated 5 out of 5 by from Best compression/ dry bag I've ever used Use these kayaking, so hold space is a premium. I use for sleeping bag and for clothes. I thought that I would get them primarily for compression and thought the dry bag was a nice plus. But it turns out that I've had to strap the one on the deck during some pretty heavy seas and they kept my gear dry. And they compress the sleeping bag into almost nothing, so they are a huge space saver. So use it as a compression sack or dry bag. Either way, the best of either I've ever used. The fact that it does both just makes it a fantastic value.

Rated 5 out of 5 by from The Best: Versatile, Durable, Waterproof As a cycle tourist and cycle commuter, compression, weight, and water resistance are top priorities for me. These bags are the best. I have one 6L sack for spare clothes; one 6L sack for my summer down bag; one 10L sack for my winter down bag; and one 10L sack for my tent, footprint, and fly (fits a 1.5 person setup or most 2 person setups, not including hardware). I originally purchased a 15L sack for my winter bag, but was surprised when it fit in the 10L sack (Just!). Because these sacks are 100% waterproof, they can be tucked into panniers or strapped to the outside of panniers or other bags. Notes: - The 15L is significantly wider than the 10L, and may not fit inside some panniers. - Also, the similar Sea to Summit UltraSIL compression sacks are more lightweight, but not as effective outside of other protective containers.

Sizing: I have the kelty cosmic down 2.0 XL sleeping bag, and am wondering what size compression sack would be best. Thanks!

Asked by: AndrewThorne
I bought the 15L (Medium) for my Kelty Light Year Down 15 Degree Long Sleeping Bag. It is somewhat of a tight fit, but it definitely fits and can still be compressed a considerable amount. In my opinion the 15L is the smallest compression sack you would want for a sleeping bag.

What size dry compression sack would you recommend for the nemo nocturne 30?

Asked by: aburrows1989
I have the same question and same sleeping bag. the nemo nocturne 30 (regular size) barely fits my Sea To Summit EVac 5L. From the capacity info, I'd think that the 6L of this would work, giving it just that little bit of extra room to close the sack nicely and not loose a kidney pressing down the bag into the sack, but from the SIZING info, it looks like this 6L is smaller than the Evac 5L. Just figured I'd share.

If I have a Marmot Helium 15 - Long and a Marmot Plasma 15 - Regular what size of compression sacks do I need?

Asked by: Mose
If you are planning on using one bag for both the sleeping bags, you would need at minimum the Sea to Summit eVent Compression Dry Sack’s 20 liter (9"x20") sack. If you intend to have one sack for each bag, you can use the 10 liter (7”x16”) sack for the Marmot Helium 15 Long and the 15 liter (8”x18”) sack for the Marmot Plasma 15. But you can use a larger stuff sack to make stuffing easier. On the trail, to keep your sleeping bag clean and dry plus have greater personal comfort, I'd recommend you put clean sleep clothes, a sleeping bag liner, and perhaps a small camping pillow inside the compression sack with the sleeping bag. If you decided to pack these items with the sleeping bag, you can use a 15 liter (8"x18") sack or 20 liter (9"x20") sack for each sleeping bag, depending on the bulk of the materials. However, avoid using a compression stuff sack for long-term bag storage because it would reduce the bag's loft.
