Sea To Summit eVent Compression Dry Sack

Used this bag last year on a week long trip into the backcountry to keep my Big Agnes sleeping bag dry. Worked like a charm as we got rained on almost every day. Actually purchased the large as well for keeping all my clothes dry on my treks as well. Nothing worse than putting on wet clothes. Very durable product that is easy to use.

One of my favorite things about camping and backpacking is the knowledge that after a hard day of hiking/climbing/shenanigans, I get to eat some good hot food and curl up in my sleeping bag. Thus, a wet sleeping bag = total bummer.

My favorite feature of this bag is the double stitching. I've seen a lot of compression sacks get cranked down to the point that they are literally bursting at the seams, but you can cinch this thing as tightly as you like without fear of rippage.

A little pricier than some of the others out there, but with good reason.

I love these things. They are ridiculously durable. I have yet to have one tear, rip, or fail in any way. They do exactly what they advertise and they do it excellently. I own the extra small and the small. The XS i sometimes use for clothes/jackets, and the small I use for either my tent or sleeping bag. They are invaluable in the rain, even though I rarely hike or backpack in the rain. I still use them on almost every trip just because they make such a durable and effective compression sack. This thing also works great as a makeshift bucket, for when you need to bury a fire in snow/dirt/water.

One important point. While these can be considered waterproof, as the Sea to Summit website states: "Suitable to keep contents dry in any wet situation where the bag is not submerged." I'd feel comfortable using them in relatively calm water, but not in rapids.

The stuff sacks are light, strong, and durable. I wouldn't hesitate strapping one to the exterior of a pack if I needed the space. I own 2 M, an L, and an XL. I can stuff a men's reg TNF Orion 20°F syn-bag + bag liner in an M. A Western Mountaineering Puma MF -25°F down bag + liner + cheapo Kelty syn-fill pillow fits in a L.

Another great use is for general travel. I used the above set of stuff sacks to suck clothing for three people down to fit in three carry-on bags for air travel to Maui. I saved enough money on baggage fees from that trip to just about pay for the stuff sacks, and it made the air legs of the trip much easier.

I bought the XS originally for my down sleeping bag, but I could only get it to close after 15 minutes of effort, so got a S and it works perfectly. Keeps everything dry and well compressed. The eVent on the bottom is awesome. I kept the XS and it works really well for keeping a spare outfit dry. I also use it on kayak/canoe trips to hold my lunch, camera, sunscreen, etc.

Really a great buy, and I've had no problems with leaking even though I completely submerged it.

I have used this in a size small for my 30* Montbell Super Spiral UL Down bag, and it functioned perfectly. Compresses my bag without much work, and has been watertight when needed. I will say that 4.5 oz. isn't a cheap price to pay, but a dry down sleeping bag and a small enough compressed size to use a smaller, lighter backpack is worth it if you need the space. I find that the 8-liter Sea To Summit Ultra-Sil Dry Sack is also a great option for my sleeping bag, and at a much lighter weight, 1.1 oz...

Compresses my Marmot Sawtooth wayyyy down and keeps it dry and protected on trips. This thing makes people say 'whoa' at how small it makes the bag. I have even dropped it in the water while carrying it from a boat to shore and it did its job flawlessly.

Last word: Staying dry at night starts by keeping your bag dry in the day. Compression means more space in your pack.

Grabbed a 20l version for my sleeping bag and sleeping pad and its great for fitting in the sleeping bag compartment of my aether 85. It compresses really easily with the eVent panel on the bottom. Had one of the just dry sacks and had problems with durability so I've been carful to use this one in my tent and then put it straight in the pack and not leave it on the ground. Will up date review after a few more trips!

I agree with many of the reviewers here. The medium or 15 liter fits everything. Most tents and sleeping bags and it's perfect for a weeks worth of clothes. Buy three of these, put everything else in zip locks and your good to go. I've had this thing submerged (not that I'd recommend it) and everything came out dry as a bone. This sack was an "Editors Choice" in 07 and it may as well be every year. It's the best.

Wasn't sure that my Marmot Arroyo was going to fit in the XS. But since XS or XL were my only options, I went for it. I just stuffed the bag in there and compressed it! I didn't even have to work very hard at it. I think I even got 3 full rolls of the collar, maybe 2... I'm really glad it fit, considering I have a down bag and I really don't want it getting wet, if the eVent arises... I might wait and see if the small comes back and I'll keep this XS for other things. Looking forward to really getting to use it!

I own two. One almost large enough to line the interior of my multi-day pack and a much smaller and more practical one to hold just a sleeping bag. Compression straps and a waterproof design, enough said.

I have a small for my 15 degree 800 fill down bag, glad I didn't go with the medium.

Easily one of the best pieces of gear I own. Wouldn't leave home without it. My original reason for picking it up was to protect my new down bag from the elements but while waiting for that to arrive I decided to toss my older synthetic bag in it for a couple of trips. What a difference it made. What once took up the entire sleeping bag section in my Arcteryx Bora backpack now only takes up half that space. No other compression sacks worked that well.

really is water proof and built very sturdy. Best in class.

I love these things! Can't count how many times someone has said 'That won't fit in that bag." and watched in disbelief as not only did it fit but then how much smaller it compresses down.

I absolutely love this bag. I have managed to pack my down sleeping bag into it and when I go anywhere I don't have to worry about my stuff getting wet. Because it is a stuff sack and the air escapes out the bottom and doesn't come back in once the contents are compressed, it saves a ton on space. Just for the peace of mind, grab a few of these and never deal with wet gear again!

A very straightforward and well built compression sack. For reference I bought a small and it's a tight fit to get my down 15F sleeping bag in it.

That's bout all I can say for this sack is WOW!!!! I'm an ol skewler and have recently gotten into the ultralite/lightweight packing in the last year. Been gearing up for the AT next year and have poured over Backcountry.com and Backpacker magazine for tips on what gear to purchase. I've never used a dry sack, ever to be honest, but knew I would need some form of one for at least my sleeping bag. I own the Lafuma X950 Pro so I bought the Small sized event dry compression sack. I haven't tried it out in wet conditions...but after all the gear reviews I have read here and various other places I am confident my bag will be safe from water. However, if you are new to roll top closure bags there is a learning curve; don't feel ashamed to have to conjure up a gear head through the online chat feature here to get some advice on exactly how that works, lol!!! Long story short, once I finally figured out how this thing closes up I pulled my sleeping bag out of its tote bag and stuffed it in my event sack. After kneeling down on my bag with one knee I was able to cinch the compression straps within an 1/8 inch of their maximum. To put it in a nut shell I just cut 6 inches vertical packing height (if I remember my math correctly that wouold be 42 cubic inches altogether since its app. 7 in diameter...may be wrong) from my packing interior of my bag. That may not seem like much but I am only using a 3000 cu. in. pack for the AT so app. 42 cu. in. is a world of difference in this pack. I guess the lafuma pack bag now gets duty for something else that doesn't need water protection. Some people may think the price for this item is steep, but to me it is worth every penny just for cuttin down on packing volume, I'll say it again, "WOW!!!!" If you're interested in this then I highly recommend because these compression straps haven't budged one bit and loosened up since I cinched it all down...nice!!!!! I will be getting more of these for my clothing and electronics.

I purchased 2 of these years ago before studying abroad in Viet Nam. I was amazed that I could pack nearly all my clothing into a XL bag and compress it down to the size of a bowling ball.
More recently I spent 9 months living in a tent in SE Alaska (a temperate rainforest). I used the same two bags plus a new one. I kept nearly all my possessions in the 3 combine bags. They proved to be amazing when my tent failed and turned into a pool with canopy and kept my stuff dry through numerous other challenges including a kayaking trip through Glacier Bay National Park.
There durability, compression, and waterproofing make these bags a great choice if you are willing to put out the extra money. In my mind there is little question. These are worth it.
I used a Medium to stuff my 15 degree down mummy bag, sleeping bag liner and pjs. It also was my pillow for 9 months.
I stuffed my clean clothing into my Large
My extra large would be used for anything that was left over.

I love that the top closes like a dry sack and then has a compression top as well. I use an Extra Large for my synthetic -30 degree and I have one of these as well as an ultra-sil Small for my Down 20 degree. Sea To Summit is an excellent choice. I also really like this bag because it lets the air out while you compress it, something my older OR sac did not do very well.

I picked this up in an XS(6x14) for my Western Mountaineering Megalite. I was skeptical about it's ability to compress, thoroughly impressed! It packs down believably small. The eVent works so great, and weighs virtually nothing. Looking forward to picking up more of them!

I've used this sack for my sleeping bag and clothes in torrential downpours, and they've even taken a swim in the colorado river, everything was still bone dry when I finally retrieved it too. Im the kind of person that wants to make sure my important gear stays 100% perfect, I trust this bag and will continue to buy them for my gear. When you look in my pack you normally see about 3-4 of these, tend to keep my food and cookware in one also, keeps the pack clean and you can just rinse the sack out if it gets dirty.

So far, High quality, packs down small, and it's waterproof... it's a compression sack

I got one of these for my down bag last minute on a whim for a mountaineering seminar I went to on Mt. Hood. The first day it was 34 degrees (F) and raining with 30 mph winds all day, then dropped to 20 (F) overnight. My only piece of gear that didn't get soaked through (and subsequently frozen solid) was my sleeping bag (awesome). I don't know what I would have done if I hadn't gotten this (frozen my unmentionables off all night long, probably). Size M was good for my Stoic Somnus 15.

These things are great. I tested it out with some tshirts in it and dunked it in a pool and the shirts were completely dry. I would trust anything that cannot get wet in this bag. This bag will keep your sleeping bag dry on all the long and wet hikes you take

I just got the medium size to throw in my pack for my clothing. If you like to bring several changes of clothing for longer trips (rather than being the smelliest person at camp), this sack should do just fine. I have yet to test the waterproofing, but other reviews have left me feeling confident that this will keep my items dry with ease.

This is a great stuff sack that I picked up on a super sale. It does exactly what is says, allows air to pass out of the bag while compressing... and remains waterproof. My sleeping bag went swimming on a canoe trip (along with the rest of my gear) and emerged dry as a bone. Durable, light, simple... just not cheap.

I have the small size and my Western Mountaineering Sycamore fits inside quite nicely. I've never had an issue with it letting in moisture although I can't say that there's really been much occasion for it to let in water. I found that it's a touch heavy for a stuff sack (there are lighter waterproof ones out there) and a bit expensive. All in all, I'm not displeased.

Bought this to hold my clothes on a trip through the White Mountains on the AT. Very simple to use. Excellent quality, and saves so much space in your pack. I can't comment on how waterproof the fabric is but I've heard good things. Besides, if all you're doing with it is using it on a hiking trip chances are it'll be in your pack most of the time anyhow. Great product overall.

Ok, to put it simple.. like the title says, AMAZING. This thing will keep your stuff dry while making it small to make more room in your pack. Just stuff your house in it and pull the straps tight and take it up the trail. fantastic. get one or two or ten.

I got the medium and small bags for my sleeping bag and clothes on kayak camping trips. Thinking of picking up a few more for other stuff. E-vent material is nice, purges air and keeps things dry.

If you have a down sleeping bag, go and buy this right now! All down sleeping bags should just come with one of these. Better than the compression bag that most sleeping bags come with. Have had this thing for 4 years so far. After backpacking in pouring rain, you'll be glad to get into your warm DRY sleeping bag.

this sack is sweet. I use it to compress my Montbell SS Down Hugger #1 sleeping bag. At first I was thinking there was no way to do it...but compress baby compress!!!! And it being water proof is the main reason I got it, keep that sleeping bag dry for a good nights sleep.

I love these little bags! I always throw 2-3 of them in my pack wherever I go, because you always end up needing them. Whether it starts pouring and you need to keep electronics dry, or you need end up having to cross a river and need to keep something dry or even if you need to pack out some trash you don't want getting your other stuff wet or dirty. Compression bags are cool, but these take it 2 steps further. 1. They are waterproof, so bonus. 2. It has the event fabric on the bottom so it eliminates all the air in the pack and makes it even smaller than a normal compression sack...and its waterproof.

I use one of these for my 15 degree Marmot Helium and 0 degree Mont Belle sleeping bags - not at the same time. There's plenty of room for an extra base layer and some dry socks along with the bag. I really like the eVent Dry Sacks for the ability to push all the air out and save space. If you're thinking about it you probably need it.

Took this bag on a four day test run down the river. The bag leaked every day. Tryed different methods of rolling the top, different number of rolls, different tightness. I worked pretty hard trying to get the bag to work out, drying it overnight and trying again the next day. perhaps I got a bum bag, but to keep important things dry, I do not recommend.

I bought this to help protect my Big Agnes Pomer Hoit 0 degree down bag (awesome bag by the way...), and it is awesome. NOTICE: It is NOT meant to be submerged by any means, and it says that in the description. It will hold up if it falls out the canoe or gets heavy rain, but when you put it under water the pressure tries to equalize and forces water into it. If you want something that works, I would go with this b/c I have used it for a 2 years now and have not had a problem with it.

I've used this bag for about a year, and have not had a problem with leaks, though, I generally don't put myself into a place where that would happen anyhow. I washed the stuff sack as my 2 year old spilled something on it (in a front-loader on cold hand wash cycle), and noticed that the seam tape had pulled away in several places, exposing the sewn seam.

Again, I've never had any leaks with it, but keep an eye on that tape. Backcountry is also standing behind the warranty as well, so cheers for them.

There are much lighter options available. Though they can be less waterproof.

I bought this sack for my down sleeping bag and works great! I recommend this to everyone.

Nice for security keeping a down sleeping bag dry and comrpessing as needed. But, remember there are lighter options out there, especially if you don't need a true compression sack. Dry sacks can be half as much weight per volume. If you have enough room in your pack, I suggest those for other items. I could justify a sleeping bag here, maybe bulky clothing in the winter too......

Used this while on Whitney and Langley. The medium weighs 4.7 oz. It fit my 3.0 lb Sierra Design Wild Bill bag just fine. I also had room to stuff some clothes in there with the bag. Although, it sometimes could be more beneficial to just stuff your bag into your pack rather than a compression sack.

I purchased both the medium and small eVent dry sacks. The medium I had specifically in mind for my Big Agnes Storm King sleeping bag. It is really amazing how small the eVent medium sack can pack this sleeping bag. Although I have not field tested it on a trip yet I see no reason that there will be any problems. The material is light weight but appears to be really tough.

The small sack I have used for clothes and again it's quite amazing how small it will compress them. Great bags. I highly recommend them.
