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).

GREAT bag

  • Familiarity: I've put it through the wringer

This is such a great bag I have used them many times and every time I am shocked at how well it compresses. They have really held up well and I have really cranked on the straps. I am planing on buying 2 or 3 more (family of 5 )

Small or Medium for a The North Face Hightail 3S? The original stuff sack says 17x9", but I think I could go much smaller...

Best Answer Responded on

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.

I have a North Face Aleutian 3s 20 degree bag and the stuff size dimensions are 9 X 16. It is too big for my backpack compartment and I was wondering which compression sack would be best and how much would it compress?

Responded on

The original size of your stuff sack is 16L, so you'd have to get something close to that. I can't tell how much it would compress, but don't expect THAT much more than your original stuff sack (unless your stuff sack doesn't compress the bag all that much).

I have a Marmot Angel Fire, 25 degree down women's bag. There's no information about stuff sack size, any idea which compression sack size would be better?

Responded on

I roughly calculated that the 14 L (Medium) should work for you!

Here's how: The current Marmot 25 Angel Fire has a stuff sack size of 7.5x16 inches. That's a cylinder with the length of 16 inches and a radius of 4 (rounded up from 3.75). This gives us a volume of 806 Cubic Inches, which is equal to 13 Liters. (If you don't round up the radius to 4, and keep it at 3.75, then you get 11 liters. Still too big for the 10L stuff sack).

I'd go with the 14L sack and you should be just fine!

Responded on

My REI sub-kilo 15 degree down bag is swimming in the medium size 11 liter stuff sack it came with. Even with my down pillow, it fits into the small 10 liter compression sack. It's a little bit of work to get it in, but my backpack is only 48 liters, so size matters. I use the small compression sack, then shake and fluff the down before bedtime.

I'm hoping to compress my sleeping bag...

I'm hoping to compress my sleeping bag even further. It's an REI Kilo Plus 0 degree bag, 700 down. How much smaller of a size can this compression sack reduce the bag? And which size should I consider getting?

Best Answer Responded on

Hey Sandra,

Personally I don't have any experience with REI sleeping bags but it looks like the stuff sack provided with that bag is 8.25 x 18 inches. A good rule to follow is to get a compression sack as close to the original stuff sack size so that its not any harder to get the bag in. I would suggest you get this compression sack in size Medium but if you are okay with a little extra wrestling the bag in you could probably get away with sizing down to a size Small.

As claimed

Does what it is supposed to do. Don't know if it's waterproof, have yet to test it, but it compresses nice.

Just bought an Alpinlite Sleeping Bag: 20 Degree Down. What size of the sea to summit bag is suitable?

Responded on

I would not go smaller than a MEDIUM however I would recommend a LARGE. I use a large for my Marmot Sawtooth long and it still gives me room to throw in a down pillow and liner.

Responded on

Western Mountaineering states that the stuff size is 7 x 13", so I would definitely concur with Pat on saying that you should get nothing below a M.
Unless you have stuff that you use with your bag like Pat does, I would think a L would be a bit excessive for that size bag when it's already stuffed in its stuff sack.

My fiance and I just purchased the Marmot Trestles 0 sleeping bag. After getting it home and reviewing it, we determined the stuff sack was not large enough (nor compressed enough) for backpacking. We'd like to keep the bag (great deal), but it may be returned if it cannot be compressed more. Any suggestions?

This sack would be a good choice, it will compress your sleeping bag to a manageable size (not as much as a down bag) and will keep it dry. For that sleeping bag it looks like you will need an XL.

Amazing

I bought this to put my clothes in but. I would have never guess how well it works. A++++ I need to buy about 3 more lol

Perfecto

I got a size Small for my Stoic Somnus 30 deg. bag, and it fits perfectly, with just enough room to spare that sealing the bag is easy. It really compresses the bag to an impressively small package without fuss. The piece of mind knowing my sleep is guaranteed to be dry is worth the cost alone.

Here's a medium eVent bag.

Original stuff size for this sleeping bag was 7.9 x 15.6 in and the Medium eVent bag fits perfectly.

Just as good as the day I bought it

  • Familiarity: I've put it through the wringer

I've owned the same size S compression sack for years and it is literally just as good as it was brand new. It's been on lots and lots of trips and I'm still so surprised how much tension those straps can handle time after time without ever busting a seem or anything!

Toss in a down jacket, a fleece and maybe another layer or two and it this size small makes for a nice pillow in a pinch.

I have a marmot tresles 0 degree synthetic bag...what size should I get for this?

Best Answer Responded on

For compression sacks, you generally start with the "original stuff size" ... which for your bag is 16 x 7.5 inches. That puts you nicely in the size Medium of this bag... (one could argue that the small would do it, but I'd argue against that). This is a great bag and the medium is the right size for your trestles 0

Solid Stuffer

  • Familiarity: I've put it through the wringer

This is my go to everything bag. The compression straps rocks, I would never buy a stuff sac without a compression feature. I have the medium and I can fit everything I need in it, and feel confident that water won't get all up in it. I took this sac backpacking on the Olympic Coast this summer and it handled the rain like a champ. It's also has held up beautifully in wet slot canyons - full submersion!

CONCLUSION: You want this, buy it. You know you want to.

What size should I get for The North Face Snow Leopard Sleeping Bag - 0 Degree Synthetic - Women's ? :) Nanne

Responded on

I would recommend the 20L/large size, so you have plenty of room. That's what I use for my sleeping bags.

Responded on

the claimed stuff size is 7x23 inches, or 161 inches. size medium is listed as 8x18, or 144 inches. you might be able to use a medium, but you safe bet would be large.

I have a Marmot Col MemBrane -20 degree down bag Regular size, what size compression sack do I need? Appreciate any advice.

Responded on

I have the large (20L) size for my down bag. It fits well with room to roll the top a few times and put in a few smaller items.

Responded on

the claimed stuff sack size for the col membrain is 9.5x19inches, or 180.5 inches. the large size is 9x20, or 180 inches. large should fit, but there probably wont be any extra room.

What size would be needed to compress The North Face Aleutian 3S Bx Sleeping Bag: Size Long?

Responded on

medium would be fine

Responded on

You might want to go to the 20L one. I use the 20L for my long Marmot sleeping bag and it fits a lot nicer and still gives me some room to throw in some other smaller stuff like a liner or pillow.

Responded on

for the aleutian, the claimed stuff size for long is 10x18, or 180 inches. the size large stuff sack is 9x20, or 180 inches. the large should work fine, I doubt you could get it into the medium.

Responded on

Chris is mostly correct. I have the Aleutian 3S 20 Degree bag, and while it *does* fit into the bag, it doesn't go in without a fight. I think I was on the verge of breaking a sweat wrestling with it.

I ended up ordering a large and it fits much more nicely. Definitely get a large for the Aleutian 3S if anyone is on the fence.
