Description

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).

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!

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 Responded on

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?

Responded on

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

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.

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 Responded on

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

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

Best Answer Responded on

My Marmot 2 person tent fit perfectly in a medium. I was amazed at how much it compressed!

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.

Responded on

I would go with the L. It will be just a little bit bigger than the stuff sack that came with your bag so it will be easier to stuff it into. It will compress down quite a bit to save you space in your pack.

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.

What size would work for the rei siesta double bag that unzips into 2 bags? Thanks :)

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.

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

Responded on

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!

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?

Responded on

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.
