    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).

    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

    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.

    Great, I just bought the same bag but -15, I'm getting the large sack.

    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.

    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!

    All it's cracked up to be!

    • Familiarity: I've put it through the wringer

    All you've heard about this compression dry sack it true: durable, functional and keeps stuff dry.

    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.

    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..

    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.

    Unanswered Question

    Just purchased the Big Agnes Wind Lip Sleeping Bag: 28 Degree Synthetic. Can you suggest which size I should go with?

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

    Best Answer

    This liner/bag, will compress down to 6x13", so you could definitely use the extra small.
