    Shave weight off your compression sack system, and make it waterproof by switching to the Sea To Summit eVent Compression Dry Sack.

    Sea To Summit used waterproof breathable eVent material to make the first waterproof compression bag without a valve—the eVent Compression Dry Sack. Close this Sea To Summit compression sack, and the breathable material vents air as you cinch the compression straps. No more soaked sleeping bag after a rainy day, and no more valve poking you in the back as you hike. On top of the water protection and low bulk, the eVent Compression Dry Sack weights a scant 5.2oz (medium size).

    • Familiarity: I've put it through the wringer

    I just bought another one of these awesome compression sacks for my down sleeping bag. I have had one for years and it is great for backpacking. It is the best way to compress a sleeping bag and keep it dry at the same time (essential for down bags). If you need to save space and keep something dry, then this is the compression sack for you!

    I got the Small (10L), and it was the perfect size for my Marmot Sawtooth 15 Degree Sleeping Bag (in the regular length).

    So good, I've got two!

    • Familiarity: I've used it several times

    I love these bags, I have the L and the M, I can stuff my sleeping bag and some clothing items into the M and then tons of clothes and other gear into the L. The compression is great and I primarily use it for hiking / backpacking. Not sure how great the waterproofing is as I've never submerged it or used it on river trips, but will update this summer after a rafting trip in Colorado.

    Great bags

      I have a few of these in multiple sizes and love them. Haven't fully submerged one yet, but when I do I'll make sure the stuff in there isn't super sketchy with water, because I'm not 100% sure it would stay waterproof. Will report back when I do try it though!

      Update: so I used one of these canyoneering last weekend, being fully submerged in Neon and Choprock canyons several times. the t-shirt smashed at the bottom of the bag had 2 damp spots on it, everything else was bone dry. Highly recommend!

      Best Bag Ever

      • Familiarity: I've put it through the wringer

      I've owned a lot of different bags, and always go back to this model...

      Its waterproof and tough. I've put my through a lot of abuse and it's still sticking strong.



      It survived racing the Continental Divide, fully exposed to the elements. And I've even dropped it in a river, and have never had a wet sleeping bag!

      Best Bag Ever

      Winter bag blues...

      • Familiarity: I've put it through the wringer

      The problem with going out in the winter is that your bag takes up a ton of valuable pack space. If you don't want to carry around a tower of power, pick up a compression sack for your bag and down clothing. I have found the Sea to Summit eVent sacks to work the best for burly 4 season bags. They can be tricky to size, but work really well to help you save space. If using a Gore shelled bag, stuffing inside out helps a ton. Handy option and easy to size up and stuff in your extra clothes and/or down clothing for the end of the day. Durability has proven itself following many trips when cranking the compression straps down to save a few extra inches seemed like it might stress the straps/stitching, no failures. Great for winter bags, but also tight spaces like small/lighter packs, drift boat dry storage bins and easily compresses down a down jacket and gloves to fit into your touring pack for those longer days (or longer stops).

      Not waterproof

      • Familiarity: I've used it several times

      Great at compressing, not at waterproofing. I've experienced water leakage multiple times when using this bag. It's probably fine for hiking as a backup when it's in your pack, but for kayaking or other activities where there will be a lot of direct water contact, beware! Go with a sack that is truly waterproof, even if that means a little extra air gets packed in.

      Sizing Issues!!

      • Familiarity: I've used it once or twice and have initial impressions

      Back Country was a little off on this one… I was told a small in this compression sack would fit the Marmot COL -20 sleeping bag. It does, if you don't want it to be sealed or be able to compress it! So if you have a sleeping bag with a lot of down fill, you may want to up-size to the larger bag. The small does fit my lighter down filled sleeping bags okay.

      Does the Job

      • Familiarity: I've used it several times

      As far as stuff sacks go, this one is pretty killer. I have no problem fitting my 20 degree bag in the medium, and also usually stuff my down jacket in there as well. Packs down small, keeps out water, fits perfectly into my packs sleeping bag compartment. All in all, rock solid.

      Very pleased

      • Familiarity: I've used it once or twice and have initial impressions

      S2S makes good stuff and I am very please with this for my sleeping bag. Thankfully, I haven't had a wet pack since I bought it, but it provides extra piece of mind because my sleeping bag is in the bottom of my pack which is the most vulnerable area even with a packcover.

      Works pretty well so far

      • Familiarity: I've used it several times

      Just to add in to all the great reviews. I have the Mountain Hardwear -30 Lamina sleeping bag. This thing is beefy as can be and I use the large. It is a very tight fit but once compressed down was totally worth it. Great product.

      So Far So Great!

      • Familiarity: I've used it once or twice and have initial impressions

      I purchased the Sierra Designs Back Country Bed Duo this spring and then set out to find the ideal stuff sack. I've never subscribe to stuffing the sleeping bag in the bottom of one's pack theory. All my pack's contents are separated into color coated dry sacks just in case I'm caught in a micro burst or my hydration bladder ruptures tragically. The eVent dry sack was the perfect solution, its remarkable how smoothly it operates. I will admit I haven't tested its water blocking properties in the field nor at home but assuming s2s is true their word this is a home run. If they wanted to lower the price a bit out the spirit of customer appreciation, I'd even buy another.

      Great

      • Familiarity: I've put it through the wringer

      I use this for my sleeping bag and it is great. Completely dry proof. I bring a second one for my clothes. I've brought it on every trip in the last two years and it has held up and has zero wear and tear. I would suggest this to anyone looking for a stuff sack.

        This thing is a beast when it comes to compressing a sleeping bag. I bought this to get a large 22 degree bag to fit into a sleeping bag compartment of a backpack. It has not been tested as far as 'waterproof' which I am skeptical, however, it is worth every penny just for being able to squeeze my huge bag down to a quarter of it's size.

        Going on a 14 day backpacking trip, which should see some form of moisture. I'll update the 'waterproof' aspect later.

        Perfect Sleeping Bag Companion

        • Familiarity: I've used it several times

        It made my sleeping bag half the size and took about half the effort of getting it into the factory made stuff sack. I carried it outside of my pack and it stayed dry through melting Shasta slush. I can't recommend it highly enough - even compressed dirty clothing to free up additional interior space.

        Awesome

          This works great. It fits my full-size sleeping bag perfectly. Very durable and love how it's waterproof. Makes packing for my trips quick and easy. Any time you can save space and pack more is awesome. Definitely recommend this!

          the best compression sack

          • Familiarity: I've put it through the wringer

          lugged a sleeping bag around south america for five months with this compression sack. It made the sleeping bag fit in the bottom of my pack much better and kept it nice a dry. The thicker material keeps everything inside protected.

          Hi, I have a north face furnace 20 down bag. Which size should I get?

          Best Answer

          Connor, the Medium will be able to fit that sleeping bag in there though it might take some effort. You could always bump up to the large and put some other layers in the bag that you dont intend to wear much while actually hiking. For instance, I dont really ever plan to wear my down jacket while hiking but, really like it around camp and sometimes to sleep in, I toss this in there with my sleeping bag.

          Unanswered Question

          I'm wondering what size/ or how many liters I should be looking for in a compression sack? I just bought the Kelty women's 33 degree sleeping bag. It's 9" x 15" and I need to be able to fit it into the bottom of my Osprey 36 L backpack. Thank you so much!

          Got a Mammut Alpine UL-3 sleeping bag I, think compressed size is 10.2x5.9 and compression bag that came with sleeping bag is to hard and technical for my 11 year old scout. what is right size that will make it easier on him?

          Best Answer

          The XS will be a little bigger than what came with the sleeping bag. However, if you want it to be really easy on him, go with the small. You should still be able to compress it way down and save a lot of space.

          The stuff sack that came with my sleeping bag is 7.5" x 16" so would you recommend the small or medium compression sack?

          Would the xs be too small for the Alps Mountaineering Razor sleeping bag/liner?

          What size stuff sack should I purchase if I want to use this for my Marmot Limelight 2-Person tent?

          What size should I get for a North Face Reg Kazoo 15 degree down sleeping bag. Calculated the stuff sack size to be 17 L cannot decide between the L or XL.

          What size do I need for my WM puma bag MF 6ft6?

          Thanks

          Hey Danny,



          So the Western Mountaineering Puma Super MF Sleeping Bag: -25 Degree Down in a 6ft 6in version has a packed size of 10" x 20"



          This comes to be 1571 cubic inches or 25.75 liters.



          So for 26 liters, I'd suggest the XL of this stuff sack.



          Shoot me an email if you have any questions at all!

          I'm looking to buy this for my -20 Crosho Big Agnes bag. I was thinking of buying the large but I am unsure if that would be the correct size. Any size suggestions?

          The supplied stuff sack your bag comes with is 10x21.



          The large sea to summit is 9x 20 and the xl is 10.5 x 23.



          I would most likely go with the XL depending upon how difficult it is to get it in the supplied stuff sack. You are going to get it to compress down to the same size no matter what between the two. I would just look at wrestling the thing into a slightly smaller bag or having an easier time with a bit larger one.

          Best Answer

          Jennifer, It states that your bag stuffed is 10.9 liters. I would say the Medium would be the one to get as it maxes out at around 14 liters giving you a bit of extra space to get it all in and then allowing you to compress it down.

          Best Answer

          According to the REI website (http://www.rei.com/product/864138/mountain-hardwear-optic-25-tent#specsTab), it's packed size is 7 x 23 inches; I don't know how much smaller than that you can get it when it isn't sacked up in it's factory stuff sack, but I've included a picture of a Medium-sized one of these, with a regular size Nalgene bottle for a scale reference, since nearly everyone has one of those. As you can see from the pic, the medium is pretty freaking large, so depending on how closely you can get it packed to Nalgene size, I would go with the size closest to that.

          Hope this helps.

          Best Answer

          Personally I try to get a stuff sack as close to the original size as possible because what that is going to effect the most is how easy it is to stuff your bag into the sack. That doesn't mean you can't go smaller because obviously the bag will compress and fit into a much smaller space, but its a matter of how much do you want to wrestle with your bag in the morning to save an inch or two? Personally I would rather spend that extra 30 seconds sipping coffee in the morning and go with the Medium but I also have a 90L pack so space isn't an issue.
