The Hightide is an extremely waterproof and spacious duffel bag which will keep your equipment dry. Despite that it is designed for water sports, it is useful at any time when you need extra protection from the elements. The main fabric is completely waterproof. We reinforced the structure with sealed seams. The bag has a large U-shaped opening which makes packing easier. There is a pocket on the outside of the lid for access to important items for example, keys. There is a mesh pocket inside the lid which will help organize things. The duffel bag also has a convenient internal pocket , in which you can pack the whole bag when it's empty. You can carry the Hightide using the comfortable padded handles or attach the shoulder strap. Even though this duffel bag is extremely waterproof it is not completely waterproof if it is completely immersed in water.
