Great comp sack
Dennie
Member since
Inexpensive, easy to use, and has withstood lots of abuse from me trying to compress the bejeezus out of my clothes. Never had any problems with leakage into the bag and it works great in very humid enivronments, keeping your stuff nice and dry. It takes a bit of care to really get a nice air-free pack but you can get two sacks for the price of one that has those air releases.
have only used these for camping and personal travel so cannot speak to their durability/use in backpacking situations.
Works great

Got a 15L and it compresses my 15 degree down bag down to about the size of a kid's soccer ball. Very light and the materiel seems sturdy. Haven't tested the water resistance yet but seems air tight.
Maybe not...

I returned a 10L and 15L after the 10L tore at a compression strap on first use. Maybe the one i got was defective, but beyond that they're pretty bulky compared to other dry compression sacks I've used. They'd probably be good for sailing or boating, but i wouldn't recommend them for backpacking or mountaineering.
Good Deal

Picked one of these on SAC. Got my my REI Sub Kilo +20 down bag AND a thermolite reactor liner into the 10 L Sac. Granted, I sit on it while I tighten the straps, and when I did this while buzzed the attachment point for one strap ripped but it still works fine and did not compromise the waterproofing.
TIP: tighten each strap a little bit and rotate trough all 4 rather than cinching one down all the way.
Solid

wasn't wanting a bag as heavy as this, but if you want heavy duty dry bag, this one is real solid. One con is that it doesn't breathe at all. Not sure if they can make dry bags that do breathe... anyway, if there is any moisture in the bag, it will condensate everything else you have in it.
Good Stuff

It crams your stuff into small spaces and keeps water out, get some!
Worked great on my last raft trip!

Recently went rafting on the upper Klamath through some class 3 and 4 rapids and this bag held up good! Everything inside was perfectly dry. The compression straps are not only nice for making the bag smaller, but you can use them to hook other things on; I looped my spare sandals though one strap and then used a carabiner to attach the bag to the raft. I like this design better than the "Stoic WPF Compression Sack"
Not a great design
kevp17107

As dry bag compression sacks go, this is not a great design. It does not have a purge valve or an air-permiable membrain to let the air out. It has a drawcord closure abuout 2/3 of the way up the inside of the bag, and the idea is that you put your items in, close the drawstring, and then compress the bag. Finally, you close the roll-top closure to make the bag waterproof. The internal draw string is not easy to use. It is a very cumbersome method. You can not compress the bag once the roll top is closed. The Sea to Summit bags are a much better design.
Do these bags have a valve?

This bag does not have a valve. It works sort of like a regular stuff sack. If you fold down the roll top portion of the sack, you'll find a draw cord that you can cinch. The compression straps are attached to this portion of the bag. So you cinch the cord tightly, then use the compression straps to compress the bag. Excess air is expelled through the top where the draw cord is. Once compressed, you then use the roll top portion of the bag which is welded to the main bag to make it water tight. It's kind of a weird method but works.
Great for river trips

These bags are perfect both in their compression attributes, as well as being light weight and waterproof.
Stoic 10L Compression Bag

Wicked!

The 10L is not very effective for sleeping bags. I would recommend the 15L, unless you want to spend 10 minutes packing your bag that won't fit.
Flyfishun
Member since
I agree with jaspergibs. Some sleeping bags may fit inside this. My synthetic 15 deg. Sierra Designs long does not. At the price I paid, it won't be worth it to return it. I may use it to hold spare clothing on float trips.

Maybe i should have been more clear - i am a woman - and i put my women's specific down bag in this compression sack.
