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 piece of kit

  • Familiarity: I've used it several times

Used in hot dry weather so unable to comment on water proof abilities. Compresses clothing well.

Best Piece of Gear I Own

  • Familiarity: I've put it through the wringer

I have 2 of these. One I have been using for around 4 years. I bring it on every single climb, hike, camping trip, etc that I go on. It is solid. I usually use it to store my down sleeping bag. It never leaks and has shown no wear what-so-ever. Worth every penny.

WHAT SIZE SHOULD I BUY FOR MY MEC ZIZ SLEEPING BAG

Best Answer Responded on

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.

Stuff your sack.

I have quite a few dry bags for kayaking but purchased one of these for mountaineering and hiking for stuffing and compressing the sleeping bag.

I don't think I will ever use this thing for using in the kayak, Nope, it just doesn't seem durable enough. For stuffing it in your backpack, no problem.

I got the Medium for my Marmot lithium 0 degree down bag. It does make it a bit smaller than just stuffing it into the stuff sack it came with. Every bit of space counts when you are trying to fit everything in there.

solid stuffing

  • Familiarity: I've used it several times

I haven't had the chance to test out the water repelling capabilities of these yet, but they can compress really well. Having an eVent jacket, I'm sure these will stay dry really well too. I've already gotten two sizes in these, and plan to get at least one of each! Will post again when I find out what happens when trying to get them soaked.

what size for the new Mountain Hardwear Optic 2.5. if anyone has one im sure you can see the sack it comes in doesnt compress and is far too big for it. but love that tent!

Best Answer Responded on

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.

Fits Nemo Mezzo Loft 30 sleeping bag

  • Familiarity: I've put it through the wringer

20 Liter is a tight fit but works. Once compressed, fits nicely in the Gregory Baltoro 75 pack's sleeping bag compartment (bottom of pack). Side note, Sea to Summit 65 Liter eVent makes a great pack liner on top of this product. Cheers.

What size compression sack to get for an older Kelty sawtooth 20 degree bag? Finished size is 32 x 84 inches. Weight of filling material is 48oz. Filled with Polaguard.

Responded on

I believe the original stuff sack was 7.5 x 16 inches which would put you in the small compression sack for this eVent compression sack.

Swear by these things

  • Familiarity: I've put it through the wringer

I use these things exclusively for my backpacking trips. I don't know what others are saying, these things are super waterproof. I have never had an issue. I use one for my food and one for my clothes. I hang the food bag when in bear country. I have had it snow, rain you name it and I have never had an issue with even noodles getting humid. These are great and to me a must have for any one that spends time in the BC.

eVent not waterproof

  • Familiarity: I've used it several times

So I had to hike 5 hours in the rain and everything in the bag was dry except my clothes that were near the eVent. I am quite disappointed about it. I guess next time I will put a plastic bag on the bottom (but then what is the point of having a "dry" bag).

Responded on

The purpose of the eVent (pay close attention to the word VENT in the title) is to keep everything INSIDE of it dry. It does this by expelling water from the surface of the bag. So it's best kept in it's own compartment (sleeping bag compartment or the top single pouch of a pack) so that nothing around it gets wet if there is a very heavy amount of rain/humidity/etc.

Responded on

Well Travis... if you are clever enough of course I am talking about the things that were INSIDE the bag. Those ones got wet! But you know what? And this comment is for everyone else... I contacted Sea to Summit directly and they recognized the eVent of my bag had a product defect. They kindly sent me another one to substitute it without any additional cost, and guess what... IT IS TOTALLY WATERPROOF. Thank you so much to Sea to Summit for that wonderful customer service response!

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.

Responded on

I was going to ask the same thing. The North Face Hightail 3S stuff sack is 26 L, so I wonder if even the M would be too small. Which did you go with?

These Are Awesome!!

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

Pros: Great design! Easy, fast and efficient to use!!!

Cons: A little pricey!

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?

Best Answer 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 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

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

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?

My fiance and I just purchased the Marmot...
Best Answer Responded on

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.
