Granite Gear Air Compressor Compression Sack - 2006

Great lightweight addition to their already bombproof Round Rock Solid compressors. These have proven themselves to me for over three years without any problems. I own one each of the XS, S, & M. The medium can be used for all but the largest sleeping bags. I use the XS & S for clothes & fleece items. Extremely lightweight & durable. Items are visible due to the more sheer SilNylon material. I don't recommend FULLY compressing the higher loft down sleeping bags for fear of damaging the more delicate clusters. Just a thing of mine!

I took three of these XS compression sacks with me on my thruhike and in one I kept all my clothes, in another my MSR Hubba including the footprint, and in the last my Horse Thief Big Agnes sleeping bag. Surprisingly waterproof as my bag was soaked on more than one occasion. These things are bombproof and never threatened a blow out. I used the hell out of them and they are still super strong and seem as new as when I first got them. Recommend to everyone.

I bought this sack for my down sleeping bag, and at first I thought it was just too cool. See through material, a reusable container...I was a happy camper. Until it ripped that is. It tore after about 1 year of use, and it happened near the edge, where I was gripping it with my left hand as I stuffed it with the right. The nylon just came off in my hand. Since then I replaced it with an Outdoor Research Helium stuffsack, and I couldn't be happier. Another neat feature that the Helium has that this one lacks is snaps on the straps. The straps on the air are all permanently attached, so every time you put the "cap" on, you have to make sure they're untangled and aligned. A stuffsack that has snaps is just so much quicker to pack up.

I can fit my Kelty Gunnison 2 tent, fly, and footprint in this little bag, then cinch it down so small...it easily fits in the bottom of my pack!

These things are absolutely fantastic. Made of sil-nylon they are lightweight, strong and squish your poofy stuff down to nothing. I can get my -20 down bag into a small and squish it down to less than half the full size. Glad I bought two so I can use one for my down jacket & clothes. Surprisingly durable.

The medium was a bit smaller than I'd hoped for. Couldn't get a sleeping bag into it, so I compact my socks, underwear, a towel, beanie, and a sweater; so it worked itself out.

Compresses as good as any other sack, see through material, they're durable, and they're feather-light! FANTASTIC!

I love this bag. I use it for my XL down jacket, my XXL rain jacket, my rain pants and a beanie. It works great and is pretty tough for being very light weight. It helps me cram more into my pack.

I keep my 3 man tent in this and manage to fit my sleeping bag, pad and tent all in the sleeping bag compartment of my regular size backpack. It is really lightweight and weighed less than the stuff sack the tent came in but it can still compress everything.

I love these. They're great for organization, reducing bulk/volume, they make nice pillows, and they look cool. Super-light, and breathable (put wet/damp clothes in one and toss it in your sleeping bag, be your own dryer). Extra nice.

I can fit my Marmot pinnacle in the small sized sack with room for a jacket. I have had other compression sacks that come apart. You can't go wrong with this. Sil-nylon is what it is made from. It is the coolest stuff.
