The birth of Monthbell's waterproof trekking pack. The combination of the waterproof inner bag and roll up closure effectively prevents water penetration. Without a top lid, the roll up closure also allows for quick access to your pack's contents. Ushering in a new generation of backpacks. This model is made with a lightweight and strong material, and achieves an exceptional weight balance that provides stability and prevents you from feeling the weight of a heavy load. Features a convenient pocket for storing small items at the front and a zipper for quickly accessing the pack's contents from the bottom of the bag.
