Sealline BlockerLite Dry Sack
Lightweight waterproof dry sack for organizing you gear and keeping it from getting wet. Made of 20D silicone and polyurethane coated nylon to keep the weight down, with fully welded seams - not sewn and taped - for durablility. The bags are shaped like squished sausages, not round, so they don't roll down the bank when you're unpacking.
