This backpack uses DSM's Dyneema composite fabric (formerly Cuben Fiber).
Dyneema composite fabric, a film made by laminating Dyneema fibers with UV resin, is used in high-performance sails for racing boats, and is ultra-lightweight, highly waterproof, and has high tear strength.
This backpack is made with priority given to lightness, so if concentrated force is applied to one point, there is a risk of damage such as holes.
The zipper on the side of the front pocket allows you to access the inside and take out your belongings.

Actual capacity 25-32L
