Used only once this season for river trekking. The condition is as good as new. Please note that there is some minor mud staining from use. This mesh pack can be used with waterproof bags such as the "Light Dry Bag" for various water sports, including river trekking. It features full-fledged functions for comfortable carrying, such as S-shaped shoulder harnesses and a back structure with spaces in the pads to reduce stuffiness. Both use 3D mesh fabric, which does not retain water even when wet, keeping it lightweight at all times. Water drainage mesh is placed at the bottom. Pads are inserted into the shoulder harnesses to reduce the burden on the shoulders, and a plastic panel is inserted into the back to pursue a more comfortable carrying experience. *Waterproof bags are not included.
