25L Outdoor River Trekking Waterproof Bag Backpack Camping Hiking Backpacks Dry Bag Drifting Swimming Bags Double Shoulder Strap

• 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 don't 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.
• NEW LARGER 30L SIZE: We've tried the 10L and the 20L backpacks. But they're just not big enough. With our 25 Liters dry sack you can pack in more things.
