Crafted from durable, lightweight Oxford Nylon fabric, soft Polyester or luxurious silk with a waterproof, stain resistant TPU film on the inside, many COCOON  travel organizers are completely welded (with a few exceptions) and feature water repellent zippers. 

The lamination, welding and the use of water repellent zippers protect your luggage and its contents against outside moisture as well as against liquids, dirt or dampness from the inside.
