Pe/Co 20L Daypack 'Dark Khaki'

The warp is polyester, the weft is a blend of cotton and nylon, and the back side is coated with 0.5mm TPU.
It is a hybrid material that is waterproof with a water pressure resistance of 10,000 mm, but has a blend of about half cotton, so you can enjoy the change in color and texture over time.
