Wetsuit hanging black

A black wetsuit hanging hints at readiness for water activities like diving and surfing, essential for thermal protection.

About this subject

The wetsuit is an essential piece of equipment for water sports enthusiasts, particularly in cold waters. Invented by physicist Hugh Bradner in the 1950s, the suit uses a layer of neoprene rubber that traps a thin film of water between the body and the fabric. This water is warmed by body heat, creating an insulating barrier that reduces heat loss.

In Brazil, wetsuit use is common along the southern and southeastern coasts, where water temperatures can drop below 20°C (68°F). Recreational and professional divers rely on these suits to extend immersion time with comfort and safety. Surfers, meanwhile, prefer more flexible versions that allow ample arm and torso movement.

Neoprene thickness varies by temperature: 3mm for warmer waters, 5mm for moderate cold, and 7mm for freezing conditions. The black wetsuit is the most traditional because carbon in the rubber helps absorb UV radiation and increases durability. Proper care, such as rinsing with fresh water and drying in the shade, prolongs its lifespan.

Interestingly, different models have zippers at the back or chest. The back zipper is more common in diving suits, while the front zipper makes putting on easier for surfers. Technology has evolved to include glued and sealed seams, preventing cold water from entering.

Frequently Asked Questions

What is the origin of the wetsuit?

It was invented by physicist Hugh Bradner in the 1950s for US Navy divers, using neoprene developed by DuPont.

How to choose the ideal wetsuit thickness?

Water temperature determines thickness: above 22°C use 2-3mm; 18-22°C use 3-5mm; below 18°C use 5-7mm. Activity matters too: surfers prioritize flexibility.

How to care for a wetsuit to make it last longer?

Rinse with fresh water after each use, dry in shade, avoid direct sun, and store away from heat sources. Do not use thin hangers that can deform the rubber.
