From the Military Times Gear Scout:
Granite Gear jumped into the military market a few years back and has slowly been filling its tactical catalog with completely new equipment alongside militarized versions of commercial staples. The Block Rock Solid compression stuff sack brings the MultiCam and coyote versions of the Block Solid to the Berry Amendment clientele.
The squared-off sides of the Block Solid mean less wasted space in your bags, especially when used in pairs. To get the idea, think about packing tennis balls vs. building blocks. Available in five sizes, we used a medium to compress a bulky 20-degree sleeping bag to the size of a Nerf football. In fact, the ¾-inch compression straps and arched lids made such easy work of the downsizing that we managed to shove a warming layer, booties and rain gear in there with the sleeping bag. The wide straps made it easy to pull all the air out of the bag, and the stitching never complained with a pop or bulge of the 210-denier fabric sides.
The sack’s compression straps can be used as lashing points if you need to carry gear on the outside of a pack. We found the sacks shed rain for many hours, but the fabric will wet-out eventually, picking up some water weight, but the interior stays bone dry if you orient the long seam against your pack.
Granite Gear went the extra mile with these stuff sacks, and it shows in the use of impeccable stitching, double-sided multicam straps and branded hardware. Just remember: Quality isn’t cheap. On top of that, the Minnesota-based company sources and sews all its military products in the US. But, we’ve got beat-up, 15-year-old Granite Gear stuff sacks that refuse to die. So, if you hang on to your gear, the Block Rock Solids are worth the price. Available now, size medium $40 coyote, $50 MultiCam.
