Squeeze every possible inch of space out of your pack with the help of the Sea To Summit Compression Sack. This cinching stuff sack features four nylon compression straps to help you evenly pack down your sleeping bag or clothes, and the flip-top lid prevents strap tangling.

Bottom Line: Maximize space with this stuff sack.

Crucial for maximizing space

By:
June 18, 2009

These bags are fantastic for maximizing space in your pack. I literally can squeeze a base layer (top and bottom), microfiber towel, rain gear (top and bottom), socks, boxers, and a fresh shirt all in a medium bag. Simply pull the straps tight and you can pack it all in, truly essential for pack space. Additionally, these are water resistant, so during a storm you wont have to fear about your fresh clothes gettind soaked. They are not submersible, and not waterproof like the eVent Sea to Summit sack, but the material is cordura and nylon so water cant get through. The only difference with these bags is they have no water tight seal at the top, but as long as you have the bag tightly compressed it is very unlikely any water can get in. Add this to the essential gear list, these give you tons of valuable space!

I use this to carry my marmot 2 person tent in. It stuffs really small and saves space in your pack. The nylon/cordura is great and does repel water but is not water proof. So don't dunk it in water.

Coleman doesn't even offer stuffed dimensions on their site, but it looks like you're probably going to need a couple xl comp sacks to pull it off. The Montana 8 is like a portable condo.

Perfect for my 35 degree bag

By: Backcountry.com Employee
July 21, 2009

I got the XS size and have put the MontBell UL #4 Super Stretch 35 degree down bag in it. Packs so small you wouldn't think there is a sleeping bag in there. I am keeping an eye on the stitching per Cory Guru's review, but so far so good on a couple of trips. I have a medium size of this bag too for packing top/bottom rain gear, synthetic insulation, base layers, extra socks/underwear, and pillow case. Good quality for the money in my opinion.

How do you judge the size you need; read the answer above, but little unclear -

What size for 2011 blue ribbon TNF Cats Meow (regular)(which is bigger than the Atoll Blue) - stuff sak provided was flimsy from the start and has now ripped at strees point.

Also need a suggestion on size for clothing stuff sack - after stuffed to the max in a regular stuff sack, they are 7 x 16.

I'm from the camp that believes that the best size to get is the one that gives you the original volume you started out with. It makes it easier to stuff, and then the compression is a matter of using the straps to make the package smaller and doing the work for you.

So, for your clothing @ 7x16" use at least a small. Although with clothing, I like to put mine into an oversized waterproof ultrasil stuff sack and load them flat so they take up less pack volume. For the Cat's Meow with an original stuff size that's about 7x21", you could either just get by with a medium, or, because it's a synthetic fill, and because it's what we use for our CMs, I would recommend that you use a large and just honk the straps a little more. To see what you'll potentially get when fully compressed (in a perfect world), be sure to look at the differentials between the compressed vs uncompressed volumes in the specs above.

Just do large sacks for both bags- no fight to stuff them, still have enough in the straps to cranks them down as far as they'll go. With the tent,use a small sack.

I recommend a medium for the regular, a large for the long. This is playing it safe since I'm unsure of the exact sleeping bags you have. Different synthetics will compress to different volumes. I used the 20deg North Face Cat's Meow for comparison.

As for the tent, I wouldn't recommend a compression sack like this. Your tent won't fold in a fashion that will be more compact using this style of sack. If you still have the original sack the tent came with, it is best to just use 2 compression straps in addition.

Coming apart

By: Backcountry.com Employee
July 8, 2009

The nylon used is super slick and this does stuff very well, the sacks design is solid. Never the less, the stitching around the drawcords hem is coming apart on mine after only mild use and will soon be useless. I would not recommend this to a friend due to this durability issue.

Should be smalls for everything. Depending on what type of jacket, maybe even an XS just for that alone. A good way to figure out what size you need in a comp sack is to figure out how bulky the items you plan to put in it are going to be. Base your original volume on that. After all, x amount of gear is x amount of uncompressed space- compression is your bonus.

If you have a regular-large Encampment, your normal stuff size is 9x20" and your max compressed size is about 10x10". If you want to fight with it every time your stuff it, try the medium. If you want it to be easy, but still get it as compressed as you're going to get it, use the large sack. I would get the large and let the straps do most of the work. Hope that helps.

You can pull off a small, but a medium will make stuffing it easier and still let you compress the bag as much as it will.

One good way is to look at the size of the stuff sack that yours came in. Get the same or one size down. I'd recommend the 10L or even a 16L, depending on your particular bag.

If you're storing a sleeping bag, you should also consider a eVent bag, which is the same as this, but waterproof:

Depends on the bag. Bags meant for colder conditions have more insulation and are therefore bigger and bulkier. Looks like EMS lists the... "stuff size" on their website (under technical specs) if you can find your bag there. I'm not sure if that corresponds to the dimensions of stuff sacks listed here (I'm used to manufacturers listing the volume), but it's a good bet that it will give you an indication of what size to get.

The material used in the standard Sea to Summit Compression Sacks is polyurethane coated 210D Nylon. (Nylon by itself is not waterproof, and needs to be coated to make it so). However, not only do these bags *not* have a roll-top closure (like Sea to Summit eVent Compression Dry Sacks), they are not seam-taped either: so water can make its way through the sewn seams. (This is true of all brands of compression sacks, not just Sea to Summit products)
- If you need a basic, robust compression sack, these bags will do the job (and the lid is designed so it won't flip over and tangle, which is a nice feature)
- if you want the same degree of compression, but would like to save weight, check out the Sea to Summit UltraSil Compression Sacks (lightweight, non flip lid, but still without taped seams)
- if you want compression *and* you need to keep your gear dry, the Sea to Summit eVent Compression Sacks is the gear of choice

And if you'd like any futher explanation (honest answers, not marketing spin) shoot me an email at barry@seatosummit.com

I second the recommendation for the eVent bags. I have a few for my sleeping bag and clothes and they work quite nicely. Only about $10 more than these and worth every penny:

Eldad, Angus is correct in the true defintion of waterproof, but the material is nylon/cordura thus the actual material is waterproof to an extent, but the top is not closed like the eVent dry sack made by Sea to Summit. So if you were to dunk this or let it sit out in a storm you might have some issues. If this is in you pack while its raining, no worries your stuff will stay dry.
