Maintenance advice
Rinse regularly in clean water, do not machine wash, do not leave in direct sunlight as this speeds up the ageing process of neoprene.

Additional information

Details on thermal insulation
Wet-type full one-piece wetsuit, made of 100% stretch 5.5mm panels (with production tolerance). 5mm neoprene foam, covered with nylon fabric on both sides. Neoprene distribution: Thermospan on the bust and back to increase the feeling of warmth, 100% stretch on the entire wetsuit, smooth sleeves with Glideskin at the ends: the smooth part is to ensure it sticks to the skin and limits the inflow and circulation of water.
Construction of the zip and assembly of the wetsuit
The back zip fastener is designed so that two panels of smooth neoprene overlap to limit the inflow of water. The seams of the wetsuit are waterproof thanks to the GBS assembly (Glued and Blind Stitched):the neoprene is glued first of all, then sewn for maximum resistance (the sewing needle does not go completely through the neoprene in order to prevent water infiltration).
Freedom of movement
One-piece with separate hood (not included).Stretch neoprene side panels (very soft and stretchy neoprene) to adapt to fit different body shapes and suit various physiques. No underarm seams for easier arm movements.Pre-shaped cut on the arms and legs, with back arch for easier movements.
Getting the suit on and off
Double sleeves with zips on the arms and legs for maximum comfort while getting dressed.The elongated pull cord makes it easier to close the back zip.
Resistance to rubbing
Ergonomic reinforcements on the knees (Supratex) and reinforcement panels on the shoulders.These reinforcements limit the effects of friction related to the environment or the material. The interior seams are ended with patches to make them stronger. Wrist protection to prevent the dive computer from turning.
Weight of the wetsuit (size L)
Weight:2.13 kg (with production tolerance).
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: 2005). CLASS C certified wetsuit : A (+7 °C/+12 °C/+45 °F/+54 °F) B (+10 °C/+18 °C/+50 °F/+64 °F) C (+16 °C/+24 °C/+61 °F/+75 °F) D (+22 °C/+30 °C/+72 °F/+86 °F).
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.To avoid having to purchase different wetsuits for different diving conditions, we created the concept, with four 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.
What is a wet diving wetsuit?
This is the most common type of diving wetsuit 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 wetsuits are available in thicknesses of 0.5 to 7 mm. Thanks to their suppleness and modularity, they constitute excellent diving wetsuits.
Tips on how to get into a wetsuit
Put your foot in a plastic bag, then slip your leg into your wetsuit. You entire foot comes out without snagging! To adjust, ask someone to blow into your sleeve from the wrist.The incoming air inflates the interior of the neoprene wetsuit, immediately separating it from your skin.You can then easily proceed with the final adjustments.
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 colours of the textile parts of the wetsuit to fade and speeds up the ageing process of the neoprene. Zip fasteners can be cleaned with a toothbrush and lubricated with silicone grease.
What is the SUBEA brand?

    Bonne combi

    J'utilise cette combinaison depuis 3 ans et j'en suis totalement satisfait. Toutefois je déplore le fait qu'il n'y ait pas de surveste spécifique ou une version en 7mm cela manque pour les plongées de début ou de fin de saison.
