While most dry bags feature basic grab-and-go designs, that's not the case with the Sea to Summit Big River 75L Dry Backpack. This high-volume dry bag features a streamlined EVA foam pack harness, shoulder straps, and a removable hip belt for an ergonomic backpack-carrying option as we haul our gear to and from the water. The 75L capacity holds days worth of food, clothes, and gear while the waterproof nylon ripstop keeps everything dry and protected on our back or in our boat.
