SUPERSINGULARITY Premium Dry Bag 30L Waterproof Backpack with Dual Air Valve Inflation and Compression Sack. Gear Bag for Boating, Kayaking, Canoeing, Rafting, Fishing, Hunting, Camping & Beach PROTECTION IN WATER, SNOW, SAND and DIRT: Strong non-rip and puncture proof tarpaulin with roll-top closure for a secure watertight seal. Because you need your sandwiches to stay safe and dry. And your survival gear. But most importantly - sandwiches. INFLATION and COMPRESSION VALVE: You know what sucks about most compression sacks? They dont keep your stuff dry. You know what rocks about our dry bags? The dual-way air vent compresses to pack more stuff in or inflates to float on water. PREMIUM 100% WATERPROOF DURABLE MATERIAL: Made from 500 Denier Tarpaulin which makes our dry packs super tough and super flexible even in subzero temperatures. It also comes in Marine Blue which looks cool on everyone. NEW LARGER 30L SIZE: We've tried the 10L and the 20L backpacks. But theyre just not big enough. With our 30 Liters - 8 gallons - 1,830 cubic inches dry sack you can pack in at least 2 sleeping bags with room for more.
