Granite Gear BlocSolid Compression Sack - 2009 BCS

Seems pretty strong, sturdy enough and compresses nice. Not much else to say, Good Compression Sack.

Nice bag, served it's purpose. Should've gotten water proof ones. These bags do work great, they do the job- compressed my stuff down- but there wasn't any shock an awe with their usefulness. I'd strongly recommend combination compression sacks/dry bags- they're a little more ching, but you get a lot more bling.

Medium compacts 3 days of clothes to nothing. Although the final shape is not perfectly square (or rectangular) I like it a lot better than the round sacks. Only the compression ends are squared, the sack part is round, maybe add some seams to make it squarish?? Definitely worth the money though. I am buying a large for my 15 degree synthetic bag because the medium was alittle too much hassle for stuffing.

Nice, tough materials and easy to cram gear into. They are bigger than I thought, despite referencing the Tech Specs. The medium was way too much for my sleeping bag and ended up swallowing my Nemo 2-man tent and reducing it to the size of lightweight summer sleeping bag. True they are not specifically waterproof, merely water resistant, but I wouldn't be real concerned about that. I was caught hiking for a few hours through a pretty impressive t-storm complete with hail; between my plain ol Gregory pack and this compression sack, nothing got even close to wet.
