The canvas backpack is ideal for every day at the beach or on the boat. It is also ideal as a daily bike and school companion. This unique backpack is handmade from durable canvas and waterproof tarpaulin. The base is reinforced with a felt plate. The canvas is upgraded by us from a used sail Smaller dirt and stains can be present and are deliberate (shabby chic). The bag is wound up at the top and closed with a carabiner. It also has a small inner pocket with zip. Each sailing backpack is unique, which is why the sail seams may differ from those in the pictures. Outer material: canvas / tarpaulin. Carrying straps: navy blue webbing. Size: approx. 38 cm wide x 56 cm long x 10 cm base
