Protecting your personal belongings before and after diving remains a constant concern. The Itiwit 40L Waterproof Duffel Bag establishes itself as an innovative technical solution for divers concerned about the safety of their belongings. Unlike traditional bags, which raise concerns about moisture, this IPX6 certified equipment guarantees absolute watertightness, transforming your surface preparation into a serene operation. Imagine: your phone, keys, and change of clothes perfectly isolated from spray or a potential accidental fall into the sea. This certainty brings real psychological comfort, freeing your mind to focus on the essentials: your relaxation and safety underwater.

40 liters of usable volume
The engineering of the Itiwit 40L Waterproof Duffel Bag is based on a design specifically studied to withstand the most demanding marine environments. Its usable volume of 40 liters, with dimensions of 70 cm in height and 30 cm in diameter, allows you to carry all necessary backup equipment without overloading: spare suit, towel, energy snacks, and even a backup regulator. The moderate weight of 755 grams when empty does not penalize your movements on the deck or beach.
The true innovation lies in its composite membrane: 60% polyester and 40% thermoplastic polyurethane. This combination offers exceptional tear resistance while maintaining optimal flexibility for rolling. The triple-folding closure system, combined with the clipping system, creates a hermetic barrier tested according to IPX6 standards, resistant to powerful water jets. The adjustable straps, designed for comfortable carrying even when loaded, allow you to transport your belongings to the diving site without unnecessary effort.

A modular protection
What particularly distinguishes this duffel bag is its modularity: the 5L and 10L models of the same range can be used as inner bags to double the protection of sensitive items. Your phone, camera, or important documents then benefit from enhanced security, a valuable asset when diving in wild or remote environments.
Don’t let the anxiety of seeing your personal effects damaged by water ruin your adventure. Itiwit 40L Waterproof Duffel Bag offers you the peace of mind essential for diving with complete serenity. Available in two colors.
