Granite Gear BlocSolid Compression Sack - 2010 BCS

Granite Gear makes great compression sacks that are tough as nails. I've been using mine for four years now, and they are still going strong...!! My Granite Gear stuff sacks have survived the AT, the PCT, the CT, and numerous other shorter hikes with the same results....unbreakable. Should the day ever arrive when one should fail...it's nice to know there is a lifetime warranty. So sleep easy my fellow hikers, you are in good hands with Granite Gear...!!

Bought the large for my synthetic sleeping bag and it made it to be less than half the original size. The square shape proves to help a bit but with a sleeping bag it tends to poof out. Great compression sack all around.

I have been using this compression sack in the medium size for the last three years now (they've changed their colors a bit). It is holding up great. I've used it mainly for my 25 degree synthetic mummy bag. This size should work fine for any sleeping bag in that range. I have really cranked on the straps of this bag and the stitching is still holding up great. This is a life saver for getting your sleeping bag inside your pack.

This is a really nicly made compression sack. The materials are pretty sturdy and the straps work pretty well. If you're using this for a sleeping bag, the square ends don't make much of a difference. I used it with my 20 degree bag and it pretty much looked the same as any other compression sack once fully compressed, but with my Marmot limelight 2-person tent rolled up it held it's shape nicely as it does with cloths also. It does seem to be a good design overall. I will be buying more to have on hand. I highly recomend this compression sack.

These are great! Work great on my motorcycle trips and when I deploy with my military unit! There design makes great use of space on the bikes and in my ruck.

Haven't used camping yet but here's what I can tell you. Every night before I go to sleep I stuff my long 0 degree bag in the medium sack. Then I crank down the straps wondering how many times I will be able to do so before they snap. Like I said it just feels cheap and if it breaks I would rather it do so in the house not the trail. There is a drawcord around the opening with the smallest stopper I've ever seen ('bout the size of a bean). Because of it's size it won't keep the opening closed. Again, cheap.
