Wetsuit hanging black

Black and hanging, a neoprene rubber wetsuit awaits the next dive. Essential for cold water diving, the wetsuit provides thermal insulation and protection against scrapes and marine organisms.

About this subject

The wetsuit, a staple for divers, was invented by physicist Hugh Bradner at the University of California in 1952. Bradner aimed to keep divers warm in cold waters and developed neoprene as an insulating material. Neoprene, a synthetic rubber, contains nitrogen bubbles that reduce heat transfer, keeping the body warm even when wet. Modern wetsuits are coated with nylon for increased durability and ease of donning.

In Brazil, wetsuit usage is common along the southern and southeastern coasts, where water temperatures can drop below 18 degrees Celsius. Divers typically choose thicknesses between 3 mm and 5 mm, depending on the season. Wetsuits come in various types: shorty (short sleeves and legs) for warmer waters, full (full body) for cold waters, and semi-dry, which feature extra seals at the wrists and ankles to minimize water entry.

Proper care extends the life of a wetsuit. After use, rinse it with fresh water and dry it in the shade, hanging it on wide hangers or folding it to avoid distortion. Never hang on thin hangers, as weight can tear the neoprene. Store in a ventilated area away from heat sources. Correct maintenance ensures the material retains its flexibility and thermal properties for many dives.

Frequently Asked Questions

What is the ideal wetsuit thickness for diving in Brazil?

For dives in Southeast and South Brazil, thickness of 3 mm to 5 mm is recommended: 3 mm for warmer waters (summer) and 5 mm for winter or colder waters. In the Northeast, a 2 mm wetsuit or shorty may suffice.

How to properly hang a wetsuit to avoid damage?

Use a wide, padded hanger or fold the wetsuit over a line. Avoid thin hangers, as the weight can tear or deform the neoprene. Always dry in the shade, never in direct sunlight.

What does wetsuit mean and how is it different from a drysuit?

Wetsuit means 'wet suit': it allows a thin layer of water inside, which is warmed by the body. A drysuit is fully sealed, prevents water entry, and requires thermal undergarments. Drysuit are used in very cold water (below 10°C) or technical dives.
