Wetsuit hanging black

Black wetsuit hanging: essential diving gear that insulates the body in cold water, made of neoprene.

About this subject

The wetsuit is one of the most important pieces of equipment for recreational and professional diving. Invented by physicist Hugh Bradner in 1952, it uses a layer of neoprene, a synthetic material with air bubbles, that traps a thin layer of water between the body and the suit. This water is warmed by body heat, creating a thermal barrier that reduces heat loss. Neoprene thickness varies based on water temperature: 3 mm suits are common in tropical waters, while 7 mm or thicker suits are used in cold waters, such as off southern Brazil or in polar expeditions.

The wetsuit’s design also affects the diver’s mobility and buoyancy. Full suits provide maximum thermal protection, while shorty or two-piece suits offer greater freedom of movement in warmer waters. Features include zippers and reinforced seams to prevent tearing and excessive water entry. Black is the most common color because it absorbs heat and hides stains, but colored suits are often used for visibility in underwater photography.

Proper care extends a wetsuit’s lifespan. After use, rinse it with fresh water to remove salt and chlorine, dry it in the shade without wringing, and store it in a ventilated area, never folded over zippers. A well-maintained wetsuit can last for years, but constant exposure to sunlight and heat degrades neoprene. Good maintenance is crucial for safety and comfort during dives.

Frequently Asked Questions

What is the difference between a wetsuit and a drysuit?

A wetsuit allows water in, which is warmed by the body. A drysuit is waterproof, keeping the body dry, and requires thermal underwear underneath. Wetsuits are common in temperate and tropical waters; drysuits are for very cold water.

How do I choose the right wetsuit thickness?

It depends on water temperature. In water above 24°C, use 3 mm. Between 18°C and 24°C, 5 mm. Below 18°C, 7 mm or more. Consider dive duration and your cold sensitivity.

How should I clean and store a wetsuit?

Rinse with fresh water after each use. Do not use ordinary soap. Hang on a wide hanger (never wire) in the shade. Store in a dry, ventilated area. Avoid folding the suit for long periods.
