Wetsuit hanging black

Black wetsuit hanging in studio, essential diving gear providing thermal protection and buoyancy.

About this subject

The wetsuit is an essential garment for aquatic activities in cold water, made from neoprene, a synthetic rubber that traps a thin layer of water between the suit and the skin. This water layer is heated by body warmth and acts as insulation, reducing heat loss. Wetsuit thickness ranges from 1.5 mm to 7 mm or more, with thicker suits offering greater thermal protection at the cost of flexibility. Invented by physicist Hugh Bradner in 1951 at the University of California, the wetsuit transformed diving, enabling longer and safer exploration in cold waters. Today, wetsuits are used in scuba diving, free diving, surfing, triathlon, and wakeboarding. Proper care extends the wetsuit's lifespan: rinse with fresh water after use in salt or chlorinated water, dry in shade (never under direct sun or in a dryer), and store in a ventilated area, ideally hung on a broad hanger to prevent deformation. Choosing the right wetsuit depends on water temperature, activity, and fit: a snug but not restrictive fit is key for comfort and performance.

Frequently Asked Questions

What is the main function of a wetsuit in diving?

Its primary role is thermal protection: it traps a layer of water heated by the body, insulating the diver from cold. It also provides buoyancy and protection against scratches and marine life.

How to choose the ideal wetsuit thickness for diving?

Thickness depends on water temperature. Above 24°C, 1.5 to 3 mm is sufficient; 18, 24°C, 3, 5 mm; below 18°C, 5, 7 mm or more. High-activity sports allow thinner suits than static diving.

What care extends a wetsuit's lifespan?

Rinse with fresh water after use, dry in shade on a wide hanger, store away from heat sources, and avoid washing machines or dryers. Minimize sun exposure and contact with chemicals.
