Wetsuit hanging black

A black wetsuit hanging represents essential gear for diving and water sports.

About this subject

The wetsuit is an essential piece of equipment for diving and other water sports. Typically made of neoprene, a synthetic rubber material, the wetsuit serves to keep the body warm in cold water. Neoprene traps a thin layer of water between the skin and the fabric, which is heated by the body, acting as thermal insulation. Wetsuits are classified by thickness, usually ranging from 2 mm to 7 mm, depending on water temperature. For very cold waters, dry suits that prevent water entry are used. Black wetsuits are most common because they absorb more solar radiation and offer discretion. The origin of the wetsuit dates back to the 1950s, when physicist Hugh Bradner realized neoprene could be used for thermal insulation in diving. Since then, it has evolved with glued seams and corrosion-resistant zippers. In Brazil, wetsuits are widely used in activities like surfing, diving, and spearfishing, especially in the South and Southeast regions where water temperatures can be low. Interestingly, the name "wetsuit" derives from the fact that the suit is designed to function while wet, as opposed to dry suits.

Frequently Asked Questions

What is the difference between a wetsuit and a drysuit?

A wetsuit allows water to enter between the body and the fabric, warming that water layer. A drysuit is sealed and does not let water in, used in very cold water or polluted environments.

How to choose the correct wetsuit thickness?

The ideal thickness depends on water temperature. For water above 25°C, a 2 mm wetsuit is sufficient. Between 18°C and 25°C, 3 mm to 5 mm are common. Below 18°C, 5 mm to 7 mm or a drysuit is recommended.

Is a black wetsuit better than colored ones?

Black wetsuits absorb more solar radiation, helping retain heat, and are more discreet in the water, preferred by divers and spearfishers. However, bright colors can be safer for visibility in rescues.
