The Big River Dry Bag is a durable dry bag with a 420D nylon fabric with TPU lamination. Unlike the lighter dry bags that are designed to be stored in a backpack or bag, the Big River is strong enough to be used without external protection. Suitable for canoeing and kayaking, rafting or motorbike trips and more. This dry bag has attachment points along the sides so it is very easy to attach the bag to a vehicle or to the outside of the bag. The bag also has a roll top mechanism that prevents water or dust from getting in.
