Rock solid, but also rock heavy!

  • Familiarity: I've used it several times

This is a super tough compression sack. I've used it maybe 4-5 times so I can't comment on the longevity, but it feels really burly and seems like it'll last quite awhile. The only downside is the weight... it's got long straps, good buckles and a zip pocket at the top, which are all awesome features, but that definitely takes it out of ultralight or even "light" contention. That said, it feels like it will outlast me and at that price point, it's pretty awesome. I got the medium and I can cram by big fluffy zero degree down bag in it no problem. I don't think a zero degree bag would fit into the small unless you wanted to go to battle with it every time, but I could fit my 20 degree down bag into a small no problem.

What would be a good size for a standard sleeping bag?

For most synthetic mummy bags I would go with a medium. For a synthetic semi-rectangular bag I would go with a large. For a down mummy I would go with a small. For a down semi-rectangular I would go with a medium. Lots of differences between bags though. Give me a shout and we can discuss further.

I'm trying to compare this to other compression sacks, which have size listed by volume. Do you happen to have a liter size on these? (I think I may need to look at a size large).
Thanks!

Hey PS,

Rough math based on dimensions lists these as follows:

S = 10L
M = 20L
L = 35L
XL = 45L

What size would best fit a Kelty Cosmic 0 sleeping bag? I am getting ready to order the bag but it doesn't come with a compression sack(So I have read in the reviews.)

Hey wil1412600556,

I would suggest you get this compression sack in a size large so you can compress the Kelty Cosmic 0 bag down. I hope this helps.
