    Super Stuffer

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

    It did exactly what I hoped it would. I put our double sleeping bag into it and saved a ton of room for car camping. I've also learned through experience that a compression bag can help keep stuff dry if submerged.

    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.

    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!

    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.

    Awesome Compression Sack

    Familiarity:
    I've put it through the wringer

    This thing is great! I've had it for a few years ago... use it primarily for compressing my old school Campmor 20º down bag. The XS is perfect for this, getting it down to a package only a bit taller then a Nalgene (is that an international unit yet?), though it is obviously a bit thicker then the Nalgene. My friends are often blown away when I pull a full sleeping bag out of such a small bag. Super durable as well, I crank it all the way down, and it is yet to show any real signs of wear. Wish it was waterproof, but I guess you can't have everything.

    Great sack!

    I haven't gotten a chance to "get out" with these sacks but since I got them a few weeks ago, I have stuffed and compressed everything imaginable. They seem very strong and well put together, you can reef of them and not worry about tearing something. All in all, I'll be buying more. I was also able to get my Mountain Hardwear Lightpath 3 (body, fly, footprint) in this thing and squish it down to nothing. In the picture is the XL with 3 sleeping bags.. Sierra Designs Arrow Rock 30, and 2 SD Big Dog 35's. It took some effort but I think it did a great job.

    These are like little miracles. I am traveling with my pack as my luggage on two weeks in Central America and it is amazing HOW much room I have saved with these packs I even have room to spare. Though they are difficult and/or darn near impossible to compress to a 1/3 of the size of their original size, packed, they still compress easily to 1/2 of the size.

    Does the job

    It seems pretty sturdy. I got a 16L to store my 10 year old synthetic bag that is neither light nor small/compressible. It goes in extremely tight and with compression I thought maybe I would pop the seems but its holding just fine. Compression in that one only goes down perhaps 1/4 but that obviously depends on the bag. Id buy one again. Great price, decent product

    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? Shoot me an email anytime you have questions! Jared D.

    What size compression sack should I use for my Big Agnes Beeler Gulch 5 degree bag? It is a synthetic bag. It also a traditional bag. Not the big Agnes sleep system type of bag with the pad sleeve.

    On this page I see a default stuff size for that bag of 21" x 10" http://www.backcountry.com/big-agnes-beeler-gulch-sl-sleeping-bag-0-degree-synthetic Generally speaking, you should buy a compression bag that matches the default stuff size of your sleeping bag. In this case, that would be a 22L sack.

    What size compression bag for a Marmot CWM MemBrain 800 Fill Down sleeping bag (Long). I tried a 35L sack but it was a long hard wrestle! Is 50L too much?

    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.

    Compression Sack Size for following specs: MARMOT 20*F Sorcerer ?Sleeping bag shape: Mummy ?Sleeping bag style: Synthetic ?Insulation: Polyester fiber batting ?Temp rating: 11-20 degrees ?Shell material: Polyester ?Lining material: Polyester ?Girth (shoulder/hip/foot): 60/57/39" ?Fits to: 5'6" ?Length: 75" ?Stuff size: 14x8-1/2" ?Weight: 3 lb. 2 oz.

    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! Charlene

    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.

    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.

    the 9L and 11L are 15in and 17in respectively. But how small do they actually compress? What is the size you can get them down too?

    That's subjective and depends on what it is you're trying to compress, ie: down, synthetic bag, tent, heavy clothing, wool socks... Rule of thumb though: if the gear in it cooperates in some perfect world scenario, plan on having a cylindrical wad about 1/3 the size you started with.

    What size would be good for the marmot limelight 2p tent (body, footprint, fly)? The packed dimensions of the tent is 7x21, so minus the poles I dont know what size compression sack to use.

    The Medium on this one,too. aka 16L, aka the red one on its side in the picture. As much as you might want to go smaller, this one will be less of a fight, and you'll run out of compressabilty on the tent before you run out of strap to compress it with.

    was asked to get a 15 lb compression bag. Yours are listed as 11L, 16L, etc. Does the L equal Lb? If not, which is closest to 15 Lb. He already has a 20 Lb bag

    The L stands for Liters - how much it will hold. You typically want to size bags by volume, not weight. I'd recommend checking the dimensions in the tech specs box (above and on the left of the page) to figure out what size you'd want.

    So I need a way to pack 3-5 days of clothes and make it as small as possible. Can these bags work on clothes? If so what size should i be looking for to pack that amount of clothing?

    Oh man are they ever great for clothes! Depending on how you're going to load your pack, you can compress it down into a tight bundle, or just use it to keep everything together, but still stuff the nooks and crannies. For what you need, I would go with the large. These comp sacks are fantastic. You'll be hooked the first time you use it.

    Yeah, they'll work for clothes. Depends on what type of clothes you have for sizing. If it is mostly down and highly compressible stuff then you might be able to get away with a medium, otherwise go with the large.

    How do these Granite Gear sacks deal with wet conditions? Are they waterproof at all?

    I wouldn't recommend using them for a canoeing or rafting trip down the river like a dry sack, but they will work fine in any other damp or humid environments. They are water resistant not waterproof.

    To add to that, the material used in the Granite Gear Round Rock Solid Compression Sacks is waterproof (PU coating), but the seams are not. They are taped (not the same taping as in a waterproof jacket) which helps them from fraying and allows them to be more water resistant. However with prolonged water exposure, the seams will draw in moisture. Granite Gear does offer a more waterproof compression sack that is fully seam taped (waterproof taping). These are the Granite Gear EVent Compression Dry Sacks. These are significantly more waterproof and feature a roll-down closure, eVent material on the bottom of the sack to allow for purging of the air, and every seam is taped for maximum waterproofness. I would recommend using these if going on a trip that will likely involve large amounts of water exposure.

    If the medium doesn't work, try using a large. This will also give you a bit of extra room for compressing a few other items.

    Do you really need a gear head to answer this??? If a Medium is too small; get the next size bigger!

    how do I know which size to get if I already have my sleeping bag?

    That will depend entirely on the size and type of your sleeping bag. I would use the following guidelines. Medium (16L): Synthetic mummy bag rated from 15 to 25 degrees. Down mummy bag rated around 0 degrees. Small (11L) : Synthetic 40 degree bags, Down 15 to 25 degree bags. Large: Synthetic 0 degree mummy bags; **Note, This should help get you into the right range, but remember things like whether you have the short, regular, or long version of your bag will also play into the equation. I have both a small and medium version of this compression sack and they have been able to cover all of my needs thus far. Remember Back country has a great return policy if you end up having to re-order.

    Just adding to what's been previously stated, the type of sleeping bag you currently have dictates what size compression stuff sack you will need. Use the stuff sack that came with your bag as a guide.

    Forgive me, fairly new camper. How do you know what size to get...looking for one for my sleeping bag.

    That will depend on your sleeping bag. If you have a synthetic mummy bag rated somewhere around 20 degrees a medium (16L) should be perfect. If you have a down bag with a similar rating I am fairly confident that you can go with a small (11L). This is a picture of a womens long 20 degree 600 fill sleeping bag in a medium. You can see that I am completely compressed as far as this compression sack can go (granite gear medium 16L), meaning I probably could have fit the same bag into a small no problem.
