    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).

    Undetectable Extension Charm

    • Familiarity: I've put it through the wringer

    These things are fantastic! The eVent material makes it super easy to compress down as much as possible and is completely waterproof. Keep that expensive down sleeping bag you bought dry! I bought the M/14L and I can fit my 20 degree down bag and my 2 person MSR Hubba Hubba with the rainfly in one waterproof pacakage!

    Perfect for sleeping bags

    • Familiarity: I've used it several times

    This is the best sleeping bag compression sack I've ever owned. It's waterproof (not submergible), compresses down really well, and air can get out! I stick my sleeping bag and pillow in it, and I have enough room to toss a puffy in too, if I needed to! I have the Marmot Phase 30 sleeping bag, and I bought the Small (10L) sack.

    10+ years old

    • Familiarity: I've put it through the wringer

    I have had one of these now for about 10+ years. It is so magical fits lot and has traveled the world, I am not sure what I would do without this magical compression bag.

    sleeping bag protection

    • Familiarity: I've put it through the wringer

    Just like everyone else, I use these to protect my sleeping bag in the rainy backpacking season. It does the job well. I own one in every size now, they are dependable and easy to use. My 0 degree bag fits in the medium perfectly, the small holds my summer bag, my wifes -20 fits inside the large very well. just wish they made them in different diameters across the same sizes.

    An Essential For Backpacking

    • Familiarity: I've used it several times

    I have this compression bag in two sizes. It has done wonders for keeping my related items together and extra compressed while backpacking or bikepacking. I haven't tested the waterproof capabilities, as my panniers are waterproof and I have a rain cover for my backpack. All the same, the waterproof aspect does give me some extra peace of mind when using the compression sacks!
    It has even rendered some of my more outdated gear (hello 90s Kelty sleeping bag) into things I can easily bring on my adventures. I managed to stuff that bulky synthetic bag into one of these and turn it into a size my panniers could manage!

    Priceless!

    • Familiarity: I've put it through the wringer

    This is undoubtedly apriceless waterproof compression sack. It. kept my down sleeping bag dry in a snowstorm on a six mile hike to camp on the outside of my pack. In return it made me very happy and cozy on those cold nights.

    Perfection!

    • Familiarity: I've put it through the wringer

    I use this bag for traveling so I can overpack clothes and get everything into one bag. It compresses like a magic trick and even with the lightweight material and nylon straps, it really holds up to abuse. The bag itself is so light that it doesn’t effect the 50lb limit per checked bag challenge. As a life long over-packer that means a lot!

    Works like a charm

    • Familiarity: I've put it through the wringer

    I bought this the replace the stuff sack that came with my sleeping bag. It effectively shrunk the size of my packed sleeping bag in half! Great for backpacking, the compression straps work great and it is water proof which came in handy on the multitude of float trips we took on the Green River this summer.
    Just a note, you shouldnt store your sleeping bag in this type of bag while you are not using it on a trip because it will reduce loft if kept in it all the time.
    It is also a water proof membrane type fabric so is still pretty light weight vs a typical rubber dry bag.

    BadArse compression & Dry as a bone!

    • Familiarity: I've used it several times

    picked up a medium for sleeping bag and a large for clothes on 1st bikepacking trip. the compression is incredible and easiest i've ever used. luckily didn't need to worry about the waterproof but a pre-ride test was no issue for the bags. fit perfect in the touring panniers and tucks nicely behind my seat in the kayak!

    Keep it dry

    • Familiarity: I've put it through the wringer

    The medium is great for my down sleeping bag, sleeping pad and one down puffy jacket. They all fit into the bag and compress down to a respectable size for packing. The small works great for my personal clothing, book and toiletries while Canoeing, I did not have any issues keeping my clothes dry on a 6 day trip with lots of rain. One thing I wish was possible is that you could take off the compression portion so that it could just be a dry bag, it would be very versatile.

    High Quality

    • Familiarity: I've used it several times

    I purchased the 14L for backpacking and have absolutely zero complaints about this compression sack. The eVent material is lightweight, durable, and keeps my stuff dry. I can comfortably fit a Mountain Hardwear Ratio down sleeping bag with a little extra room in the 14 L size, and it compresses nicely for space savings in my pack.

    Kept my down bag perfectly dry

      I used this bag while floating the San Juan a few weeks ago and had incident where the bag went overboard and floated/submerged for about a minute. After opening it up that night it was still perfectly dry.

      Sleeping Bag Armor

      • Familiarity: I've used it several times

      Finally got a STS product after hearing lots of great things. This bag has not disappointed. I have a Klymit KSB 20 sleeping bag and I got it to fit in the size Small, but it would have been tiresome to stuff it in there every morning in a tent. I went with the size Medium and it fit nicely! I can even put my pillow in there too.

      I could see these being handy for multiple uses. Clothes, down layers, electronics even. They really are easy to compress and so far it has stayed dry.

      Size matters

      • Familiarity: I've put it through the wringer

      So I recently upgraded my sleeping bags. For winter camping a 0° marmot Lithium and summer the 40° marmot atom both are longs. It's important to me to be absolutely sure my sleeping bags will always be dry, which led me to replace the stuff sacks that came with the bags. I have a spare 20 L dry bag this was impossible to use, I couldn't control the compression, roll the top up and bleed the air, in the end the whole thing just ended up to big. After talking with my gearhead he recommended these compression sacks. The E-vent works great let's air out not in so you can roll the top-down then cinch those straps down for a very small package. Use the 10 L small sack for your summer and the 14 L M for your winter bag. No I'm not a big fan of adding weight to my pack So ditch Your pillows stuff sack and stuff pillow into the bag, It belongs there anyway to help keep the pillow dry. Since I bought these bags I also realize there is a lighter weight version of this bag. I gave these two bags to my son and I ordered two lightweight ones for myself .

      The perfect compression/dry sack!

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

      I purchased the L sack and found that it could handle my Big Agnes Encampment sleeping bag and my Big Agnes Double Z Double Stuff pad with a little room to spare. This is one tough bag that can really take a beating. Once I fill it up, I don't just pull on the straps but I really press down on the top of the bag. The amount it can handle is incredible. The eVent works perfectly. Add in the waterproof and you have an incredible bag.

      Literally, a Life Saver

      • Familiarity: I've put it through the wringer

      I swear by this product for keeping my sleeping bag dry.

      My first one I used hiking the AT, 19 months of guiding in the field, and a year abroad (six months of which were spent in the bush of NZ, and the Himalayas of Nepal during monsoon season). Towards the end of my trip abroad it developed a small leaky area, which is why I'm replacing it. My pack has been in the back of a trailer for a deluge of rain, and my down sleeping bag has been desert dry. Also that one time I had to sleep under a rocky overhang on a ridgeline during a storm? Yeah, my bag was dry then too and kept me from getting hypothermic.

      Buy it. Seriously, you won't regret it.

      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.

      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?

      I'd go with the medium, so it's easy for you to put the sleeping bag in the sack. Then when you compress it, it will get quite small.

      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.

      lorp,



      How did this work out? I have the same WM bag in a regular and I was able to use the L stuff sack, but it was more challenging. I easily fit it into the XL, but felt that it could have been compressed a good bit more.

      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.

      The Medium ended up working well for me-- easy to stuff and packs down smaller than the included sack. Tried the Small and it was indeed almost impossible to get the collar to roll down enough times to be waterproof
