Sea to Summit Big River Dry Backpack

Yes, the Big River Dry Backpack is designed to be fully waterproof. Its roll-top closure and taped seams ensure that your gear stays dry even if the pack is briefly submerged or exposed to heavy rain.

It is designed for stability rather than long-distance backpacking comfort. While the adjustable EVA foam harness and sternum strap help distribute weight, it lacks the ventilation and advanced suspension systems found in dedicated hiking packs.

Yes, the webbing hip belt is removable. This is a great feature if you want to streamline the pack for shorter trips or when you don't need the extra stability.

The triple-coated base provides extra abrasion resistance and water-shedding capabilities in the area of the pack that sees the most wear. It prevents moisture from seeping in when you set the bag down on wet ground or damp surfaces.

This pack features Sea to Summit's patented Field Repair Buckles. You can replace a broken buckle in seconds using only a screwdriver, so you won't be stranded without a secure closure.

A 50L capacity is generally sufficient for a weekend trip if you are packing efficiently. However, because it is a dry bag style, you need to leave enough room at the top to roll the closure down at least three times to ensure a proper seal.
