Rated 5 out of 5 by from Compresses Very Well Another reviewer said this dry sack doesn't compress as promised, but I say that's totally untrue! It does require a bit of effort, but I've used this dry sack for 3.5 years now and it always compresses really well. I carry my down sleeping bag and silk liner in it. After securing the roll top, I lay it on the floor of my tent and kneel on top of it. I can get it so flat that I actually worry about compressing the down in my sleeping bag too much. I haven't given its water resistance much of a test, but I spilled a fair amount of water on it once and there wasn't a hint of moisure inside the sack afterward. In my opinion, this is a great product!

Rated 5 out of 5 by from A great organizer, doubles as my pillow I purchased these at a time where they came in two colors, gold, and blue. One, compresses my clothes, the other is for dirty clothes. The color coding helps to delineate the content of the bag. As been previously mentioned, it makes for a great pillow...I used to use my boots! The formula for quickly removing the air, is as follows: squeeze the bag just ahead of where your clothes leave an airspace, then roll down, and lock the clasp. Place the bag on the ground, and kneel on it with both knees. If you are using a large bag, then shift your position, until the air is expended. For me, about 15 seconds, no sweat.

Rated 5 out of 5 by from best compression sack to date! Ok, so I've now purchased MANY different types of dry sacks for my clothes for camping purposes. This is by far the easiest and most durable one yet! I've included it in everything I do that pertains to transporting clothes in my fault life. I've even let my 7 year old daughter use it on sleep overs at friends houses because of all the "necessities" she likes to bring. There is honestly not one problem with this piece of equipment. I've completely submerged it in water, and Viola! Clothes are dry as a bone! It compresses so easily after folding it, that I usually reps it to get the little extra air out. My clothes even come out just as I placed them, creases and all.

Rated 5 out of 5 by from An exceptional sack keeps articles secure and dry I bought this evac sack on the day of a cycle, camp, and hike adventure. It works as described, and is well worth the money. The 35L evac sack kept two sleeping bags secured on a bike rack, to and from camp.(see picture) The lime green sack is REI's brand. Both sacks are a great choice. My only challenge was how to throw my leg over the bike. It is a great help when the quality of your gear is top notch. You spend less time repairing or replacing, and more time experiencing the great outdoors! (see pictures 2 & 3)

Rated 5 out of 5 by from Does What It Is Designed To Do. Used this on a 7 day backpacking trip through Yosemite. I was able to place all of my clothes in it and compress it down to a nice size that would fit in my frame pack and still give me enough room for other needed items. It was also convenient when setting up camp at night to toss the sack into the tent to use as a pillow at night and to have my clothes handy (and warm) the next morning. Only complaint, which is minor, is that it took some time (maybe 30 seconds to a minute) to push all of the air out to compress it. This sack will accompany me on all future backpacking trips.

Rated 5 out of 5 by from Wish I had about 10 of these Great dry sack...much better than the ultra-sil ones. These seem much more durable and I like the venting system. **Please note that some of them vent MUCH slower than others. Test them in the store if you can...I've used a few that apparently have closed pores and really don't vent much at all (even under high pressure). If I had gotten one of those, I'd have to give it 3 or 4 stars but since I eliminated the 'bad apples' in the store...I am left with a simply amazing product.

Rated 4 out of 5 by from Air will very slowly seep back in I have a few of these, that I use for keeping my sleeping bag dry, and for my clothes. While they're great for initial compression (like, when I'm putting my sleeping bag into my sleeping bag compartment), overtime, air will slowly seep back in. This happens with all 3 of the eVACs that I own, no matter how many times I roll the top. That being said, I have yet to find anything better. These bags have reliably kept my gear dry, in rainy conditions. I have not yet completely submerged them, so I haven't given them the "what if I fall in a river while crossing it" test. If you're chances of total submersion are that high, you should consider a heftier bag, like the Sea to Summit Big River. Otherwise, this lightweight bag is great for initially compressing gear that is kept inside your pack.

Rated 4 out of 5 by from I love these I have this bag in the 13L, 20L, and 35L sizes. I use them mostly for travel (haven't tried air travel yet) instead of packing cubes. Several days worth of casual clothes fit in a 25L and many changes of "unders" in a 13L. Once the air is compressed out there's a noticable volume decrease. For what it's worth, the 13L bag will fit an ENO DoubleNest hammock, ENO Guardian bug net, ENO ProFly, suspension lines and tent stakes with some room to spare.

Questions & Answers

Once compressed and sealed, will this bag let air back in through the eVAC panel? 

Asked by: PGB
Once you have the items in the bag and begin to roll the top closure portion down the air will begin to escape out of the bottom eVent laminate fabric panel (yellow color) to allow for greater compression.

If I store wet items inside the bag, then pack it in my gear bag with dry items, can I depend on this dry bag to keep my dry items dry (keep the moisture inside the bag)?  The eVAC seems great for keeping water out, but can it keep water in?

Asked by: FormerWA
The eVent panel in this dry bag should keep liquid water inside just as well as it keeps it out. The panel will, however allow moisture to pass through in vapor form (this is why eVent works so well in rainwear), so your dry items may become damp. You will probably have better results with a standard dry bag that does not have the eVent panel.

Can you please advise what size would be best suited for the REI Igneo sleeping bag (regular size). Thanks.

Asked by: jakespikey
I have my Igneo in a 13 liter and it works quite well; not hard to stuff it into and compresses quite well. Though I have thought that an 8 liter could be used with a little effort. Hope this helps.
