Sea to Summit Ultra-Sil Dry Bag

These bags are fully waterproof. They feature a 2000 mm hydrostatic head rating and taped seams, meaning they will keep your gear dry during heavy rain or brief submersion, provided the roll-top closure is sealed correctly.

Yes. The Ultra-Sil fabric is semi-translucent, which makes it easy to identify your gear at a glance without having to unpack everything.

The oval base is designed to prevent the bags from rolling away when you set them down on uneven ground or slopes, making them much more stable than traditional round-bottom dry bags.

The bags come equipped with a field-repairable buckle. You can easily replace it in seconds using a standard screwdriver or by simply sliding the old one off and the new one on, ensuring your gear stays secure.

The bags are constructed from 30D CORDURA nylon, which offers an excellent balance of strength and weight. While they are highly durable for backpacking and travel, they are designed to be lightweight, so they are best used inside a pack rather than strapped to the outside where they might snag on rocks or branches.
