Revolutionise your packing with the ultralight and super-strong Sea to Summit 13 litre Ultra-Sil Dry Bag. You can keep gear reliably dry and organised inside your pack, perfect for backpacking, cycling touring and travelling, when you want to adventure with minimal weight. This versatile 13-litre size can fit all your clothes for a backpacking trip or a three-season down sleeping bag. It’s made from waterproof siliconised Cordura nylon and seals with a waterproof, roll top Hypalon closure, which secures with Sea to Summit’s Field Repair Buckle. The oval base prevents rolling and enables you to pack efficiently, while the slippery finish means it easily slides into tight spaces in your pack.

Not intended for situations where dry sack will be submerged under water.
