Multipurpose diving-apnea-snorkeling tube | Exceptionally comfortable silicone mouthpiece with minimal thicknesses | Upper anti-splash deflector | Transparent tube in very flexible polyurethane with mixed matt-gloss texture | Exceptional value for money | I use indistinct side. High-end tube specifically studied to achieve a perfect anatomy with respect to the diver with a completely rounded progressive profile. Upper deflector to reduce the entry of water due to waves with a studied design so as not to harm the air intake flow. Transparent tube in very flexible polyurethane with a mixed matt-gloss texture. The section of the tube walls is studied so that it maintains the necessary rigidity in the pressure area of the mask strap so as not to impair air circulation in this area. Very comfortable mouthpiece with a design that combines different thicknesses to favor self-orientation and free the user's jaw from tension. The nozzle/tube connection is especially safe against possible accidental separation. Versatile for use placed on the left or right of the face. Transparent tube clamp easy to install and very safe. Available colors: transparent-yellow, transparent-blue, transparent-pink, transparent-transparent, transparent-aquamarine, dark-black.
