It took us years of development, material sourcing and testing in different environments to develop this extremely durable 100L WP Duffel bag. It is made from the toughest 840D TPU Coated Nylon, which can take almost any beating from sharp rocks, concrete piers and boat decks. High frequency welded seams from the bottom up to the zippers are 100% waterproof and ensures that the seawater stays either in or out of the bag. The large drain valve helps to quickly drain the bag of any excess water. The extra wide lid gives a good overview and quick and easy access of your gear. The WP Duffel bag can be carried as a backpack using the adjustable padded handles as shoulder straps for the longer walks. The handles can be removed when checking it in on a flight. The internal pocket made of shock absorbing 3D Mesh material protects your dive computer or other sensitive items. The bag is easy to clean and dry out with no absorbing fabrics. All materials, parts and sewing have the same high-end quality you’ve come to expect from Waterproof.
