Adjust your warmth and the thickness of your suit!

When diving, cold is your worst enemy! Using the right thermal protection based on the water temperature, is essential. To avoid having to purchase different wetsuits for different diving conditions, we created the concept, with five 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 1mm under-shorty or a 5.5 mm over-shorty.

Tips on how to take care of your wetsuit

1) After each session, soak the wetsuit in clean water, on the outside and the inside 2) Use a bactericide solution to clean 3) Rinse thoroughly in clean water 4) Dry on a large hangar in a well ventilated place in the shade. 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. Zip fasteners can be cleaned with a toothbrush and lubricated with silicone grease.
