Our team has developed a waterproof backpack. Its use is both for everyday life and for outdoor sports. This bag is made of a very strong material, and a heat welding technique instead of the traditional sewing method to make a 100% waterproof bag + zips. The bag has a built-in laptop compartment and two small pockets. The Bodycross logo is in glossy matte black. - Composition: 500D 70% PVC and 30% polyester. - Capacity: 25 litres. - Dimension: 32*16*44cm.
