Adjust the thickness, adjust your warmth!

When diving, cold is your worst enemy! Using the right thermal protection based on the water temperature, is essential. This concept was created to keep you from having to purchase different wetsuits for different diving conditions, with 5 pieces that can be combined with your wetsuit depending on the temperature. In this way, you can complete your thermal insulation with a hood, a neoprene top, a top with a hood, a 1 mm under-shorty or a 5.5 mm over-shorty.

Tips on how to take care of your wetsuit

1) Soak the inside and the outside of the wetsuit in clean water after each session. 2) Clean with a bactericide solution. 3) Rinse thoroughly in clean water. 4) Dry on a wide hanger in a dark and well ventilated place. Caution: the sun will cause the colors of the textile parts of the wetsuit to fade and speeds up the aging process of the neoprene. Zipper fasteners can be cleaned with a toothbrush and lubricated with silicone grease
