I need more of these!

    This compression sack fits my down sleeping bag inside it perfectly, and then compresses it so it fits very nicely within my backpack.

    Canoe outfitting

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

    Just received a 16L and a 22L compression sack. Quality looks good and they pack much smaller than the sacks i have been using. Bought 2 sizes as suggested. 16 fits my 0 degree down bag nicely and the 22 stuffs my Marmot Limelite. Saved a lot of space in my pack which is more important than weight to me.

    Gotta Have Em

    • Familiarity: I've used it several times

    These things are bomber. I got the 16 L for my zero degree down bag and the 11L for my tent and I have not regretted it one bit. Money well spent and tons of space saved in my pack!

    Sleeping Bag Compression

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    I bought this for my Marmot Tretsies 15W sleeping bag, and it works pretty well! The 22L has enough extra room I can get my puffy and liner in before compressing, which was my motivation for getting an extra sack. I cannot wait to take this out on my next backpacking trip!

    Perfect for my sleeping bag

    • Familiarity: I've put it through the wringer

    I bought the 16l to compress my Marmot Ouray 0. I can pack it down pretty well. It's definitely a must-have. The stuff sacks that come with sleeping bags are worthless!

    You can never have too many

      You can never have too many compression sacks. They always come in handy some how!

      Works Well

        Did exactly what we needed it to do. Easy to uses and seems pretty durable. We'll be getting a lot of use out of this.

        Great Stuff Sacks

        • Familiarity: I've put it through the wringer

        I've had one of these for over 12 years and it still looks about brand new. I recently dug it out of my storage area where it's been compressing a sleeping bag for about 7 years without a break. When the time came to get some more compression sacks I orders a bunch more of these. They are pretty light, but not ultra light. I would say they are very tough and durable however. I'll tell you about compressing synthetics in them...The small (11L) fits a large Gortex Bivy, The medium (16L) fits a 40 degree synthetic bag well. The large (22L) fits a 20 degree synthetic bag well. All are pictured next to a 1L Nalgene for reference.

        Does what it says

        • Familiarity: I've put it through the wringer

        Exactly what I wanted. Compresses my sleeping bag and holds it there. I usually compress it as far as I can. It has held up for 3 years. .no complains.

        I have a Kelty Chinook 20 degree sleeping bag, regular size. I have a stuff sack that is 10X20 in but would like a compression sack. Can someone recommend which size to get?

        I have a Latitude Slumberjack 100% polyester 0 degree sleeping bag. The size is long and its dimensions are 68in by 86 in. Insulation is also slumberloft. I was wondering what size stuff sack would be great for only stuffing this sleeping bag? Thanks!

        great stuff sack

        • Familiarity: I've used it several times

        Durable, easy to manipulate the size, and holds my sleeping bag well. I could use a few more for my clothes, etc.

        How do I determine which compression bag I need from the liter listing??? The other Granite bags I have have a small tab indicating 'M' or 'L' on them. I need a couple black 'XL' for bed rolls and don't know how many liters an 'XL' would be ?????

        Sheldon,



        For the other Granite Gear bags you had, do you know what model they are? Unfortunately this bag isn't sized from a S-XL just in liters. Do you know the names and sizes/overall dimensions of the bed rolls you're needing a compression bag for?

        Jim,

        While a 45L stuff sack would probably work for you, the 50 in a Granite Gear Round Rock Solid Compression Sack could be great too. The Round Rock Solid sacks have a compressing lid that will allow you to compress the contents down no matter whether it is a tight or loose fit (within reason). The versatility of these bags is their greatest feature, because as long as you are within a decent range, you can use the compression lid to size down the load.

        Hey,



        That's a wealth of information, but I'm showing the stuff size for the Sorcerer at 18x8.5", so let's use that to start. That would put you in a 16L Rock Solid. The rule is to get as close to the original stuff size for the bag as possible, then, especially with synthetic fills, consider more compression as a gift. Too small to begin with, and stuffing your bag becomes a constant drag.

        I have a sleeping bag with dimensions 38" X 81". What size compression sack would i need to fit it. Thanks

        Hey Lawrence,



        We unfortunately need a little more information than the unrolled dimensions to get a real clue on what size stuff sack you need for your sleeping bag. What we really need to know is the stuff size of your bag. Most likely you are going to want the 9L or 11L bag but that's really going to depend on a lot of factors like whether you bag is down or synthetic. Is your bag a 30 degree bag? Or is it a sub-zero bag? If its down, whats the fill power? If you could let us know the make and model of your bag we could probably narrow that down for you and let you know exactly what compression bag to get.

        I am looking for a compression sack for a sleeping I just purchased that I will be taking with me on a trek into the Himalayas this coming fall.



        I am not sure what size of a compression sack I would need.

        Some information about the sleeping bag I just purchased is as follows:

        Packed volume 10.1 L

        Length 168 cm

        Fill = 575 fill-power duck down + Hyperloft Eco

        Does this mean I would need an 11 L Granite Gear Round Rock Solid Compression Sack?

        Any information you could share with me would be great. Thanks!

        Hey Charlene,



        The average stuff-sack that comes with most sleeping bags is right in the ballpark of 7 x 17 inches. You could probably get away with going with the 9L compression sack but I think you are probably right, the 11L will probably work best for your bag.

        Best Answer

        Hey too Charlene,



        Rule of thumb: start with the stuff sack size that comes with your bag to get your compression sack sizing. So with a 10.1L, yes, you'll want the 11L Rock Solid. Great comp sacks...a real staple around here. Hope this helps.
