Technical information

Details of thermal insulation

3 mm full-body one-piece wet type with back zip. Seams taped using a GBS (glued and blind stitched) assembly. Once a thin layer of water (that enters through the zip) gets trapped between your body and the diving suit, the water stays warm as it is not replaced. This thin layer of water keeps you warm.
Rolled, smooth edged cuffs, ankles and neck for maximum watertightness.

GBS (glued and blind stitched) assembly

The diving suit's GBS assembly (Glued and Blind-Stitched) means that the seams are waterproof: the neoprene is glued first of all, then sewn for maximum strength (the sewing needle does not go completely through the neoprene in order to prevent water infiltration).

More comfort when carrying diving equipment.

A diving suit specially developed for greater comfort when carrying a diving tank and wearing a buoyancy compensator.
The neoprene reinforcements are strategically positioned at the points of the BC exposed to pressure. 5 mm more neoprene on the shoulders, the collar bones and the lumbar region that acts like a cushion.

Snap hook on the upper thigh to attach accessories.

Reinforcements to reduce wear

The diving suit has printed reinforcements on the knees to reduce wear. There are also prints on the friction zones linked to the buoyancy compensator (shoulders and lower back). Also provides better body support and prevents the vest from slipping on the slides.

Freedom of movement / Easy to put on

One-piece with stretch neoprene side panels (very soft and stretchy neoprene) to adapt to fit different body shapes and suit various physiques.
The extremities of the legs and arms are also made of stretch neoprene for easier dressing.
No underarm seams for easier arm movements.

Why use a 3 mm diving suit?

Even in warm waters, the body ends up cooling down (25 times faster than in the air). Use a thin 3 mm diving suit that will allow you to delay this drop in temperature so that you can enjoy your activity for longer. In addition, use a full-body diving suit to fully protect you from UV rays and the underwater environment (coral, etc.).

Thermal performance class

This scuba diving suit provides thermal protection that has been tested by the independent INPP institute (Marseille, France) in order to validate its compliance with the current standard (EN 14225-1:2017).

This diving suit is certified for use in waters warmer than 25°C.

What is a diving wetsuit?

This is the most common type of diving suit on the market. It is not designed to keep the water out, but to trap it, so that your body then warms it up, creating a thermal buffer between you and the outside.
Made of neoprene - a rubber polymer filled with air bubbles - these diving suits are available in thicknesses of 0.5 mm to 7 mm.
Thanks to their suppleness and modularity, they constitute excellent diving suits.

Tips on how to get into a diving suit?

Put your foot in a plastic bag. Then put your leg into your diving suit. Your foot comes out completely and smoothly! To adjust, ask someone to blow into your sleeve from the wrist. The incoming air inflates the interior of the neoprene diving suit, immediately separating it from your skin. You can then easily proceed with the final adjustments.

Tips on how to take care of your diving suit

1) Soak the inside and the outside of the diving suit 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. Pay attention to the sun, because it will cause the textile parts of the diving suit to fade. Zips can be cleaned with a toothbrush and lubricated with a suitable lubricant, such as silicone grease.
