Wetsuit hanging black

A black wetsuit hanging reveals details of neoprene rubber used in professional and recreational diving.

About this subject

A wetsuit is an essential garment for water sports in cold waters. Invented by physicist Hugh Bradner in the 1950s, it was initially designed for U.S. Navy divers. Its main function is to trap a thin layer of water between the suit and the skin, which is warmed by the body, providing thermal insulation. The most common material is neoprene, a synthetic rubber with nitrogen bubbles that offer buoyancy and insulation.

Neoprene thickness varies according to water temperature: 3 mm for tropical waters (above 25 °C), 5 mm for moderate conditions, and 7 mm for cold waters (below 15 °C). Wetsuits come in full suits or shorties, with back or chest zippers. Sealed and glued seams ensure durability and prevent water entry. Black is the dominant color because it absorbs heat efficiently and does not fade from sun, chlorine, or salt exposure.

Proper maintenance extends the wetsuit's lifespan. After each use, rinse with fresh water to remove salt or chlorine residue. Dry in the shade on a wide hanger that does not deform the shoulders. Avoid twisting or using a dryer, as it damages the fibers. Store in a ventilated area away from heat sources. With these care practices, a quality wetsuit can last several years.

Beyond scuba diving, wetsuits are used in surfing, windsurfing, kitesurfing, and freediving. Thinner models offer more flexibility, while thicker ones prioritize insulation. Neoprene texture also varies: smoothskin for better sealing or jersey for tear resistance. Regardless of the application, the wetsuit is indispensable for comfort and safety in cold water.

Frequently Asked Questions

Why are wetsuits black?

Black absorbs solar radiation, helping retain heat, and is resistant to fading from chlorine and salt, maintaining its appearance longer.

What is the ideal thickness for diving?

It depends on water temperature. Cold water (below 15 °C) requires 7 mm; temperate water (15-25 °C) uses 5 mm; tropical (above 25 °C) uses 3 mm or a rash guard.

How to maintain a wetsuit?

Rinse with fresh water after each use, dry in the shade on a wide hanger, never twist or use a dryer, and store in a ventilated area.
