So far, this is the sturdiest stuff sack I've been able to find. I hope to get many years of use from it.

the 9L and 11L are 15in and 17in respectively....

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.

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.

Great sack!

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.

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

This is a must for anyone lookin to pack their sleeping bag in the smallest nook of their pack. I have the M 11L and it's perfect for a 650 down Regular size sleeping bag. I'm naturally tough on gear and after cranking down on these compression straps and pounding this thing into the small voids of my pack, its still beggin for more

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?

Phil Maher

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.

Great stuffer. I can fit a weeks worth of clothes into the large bag and have plenty of room for other gear in my pack. Rugged material too, and makes a good pillow in camp!

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.

Jason Livingston

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.

I too feel obligated to offset the mediocre ratings. This compression sack works great. Pulls enough volume out of my rather dated synthetic summer bag to allow for an extra layer of clothing or an extra liter of water. Hasn't so much as threatened to let me down.

apparently i haven't used a compression stuff sack in awhile and my old granite gear sack isn't fitting my bag no matter what i do to it (size M). so wondering if any gear-heads out there have suggestions on what size to buy for my kelty serrano 0 degree synthetic bag. any help would be fabulous!

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?

Kevin Brown

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.

You can use the XS or the Small. I use the XS for my Big Agnes Seedhouse SL2 and it's an easy fit. Ends up a bit bigger than a 1L Nalgene bottle on the height, and maybe twice diameter or so.

Traveling to Haiti with a medical group. Carrying on a small (kids!) sleeping bag. Would a compression sac make it even smaller? Thanks!

Yes, it'll make it smaller. Pretty much makes anything fabric smaller. Hope this helps!

Absolutely. I frequently compression sacks for both down and synthetic bags and I am always amazed how much smaller they pack compared to their standard stuffed or rolled up size.

Forgive me, fairly new camper.

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.

These compression sacks are the bees knees, pretty simple really; a good stuff, pull the top over, and cinch. Thats that. They are very durable, last hike I went on it ended up outside of my pack because my friends pack broke halfway through so we all picked up the extra gear, it rained, and we were bushwhacking through some pretty heavy forest, the sack came out without a tear or snag while fully compressed. I picked up a few more for various other gear.

Photo is of the 2XL stuffed with a kelty mistral sleeping bag.

Not sure why the bad ratings

Assorted colors.

Pick what size you want, and BackCountry will provide you that size in an unknown color.
