Granite Gear Square Rock Solid Stuff Sack

The Square Rock Solid Stuff Sack by Granite Gear differ from the classic Round Rock Solids in that they are designed to become square in shape instead of round when compressed. We have found the squares nest together better when you are packing more than one Rock Solid in a pack. Specifications: Size Small: Dimensions: 6.5 in. x 16.5 in.
