WETSUITS

A wetsuit is made from neoprene and fits tightly to your body, allowing only a thin layer of water inside. Your body heats this water, which then acts as insulation, helping you stay warm by reducing the amount of cold water that can enter and flush through the suit. 

Wetsuit thickness depends on water temperature and your activity. Thicker wetsuits (like 5/4mm or 6/5/4mm) are best for cold water, while thinner suits (2mm or 3/2mm) work for warmer conditions. The first number refers to torso thickness, providing core warmth, and the second to arms and legs for flexibility. 

A wetsuit allows a small amount of water in, which your body warms to provide insulation. A drysuit, on the other hand, is fully waterproof and keeps you completely dry, making it suitable for colder conditions and activities like diving or kayaking.

A wetsuit should feel snug all over, with no baggy areas, but not so tight that it restricts movement or breathing. Check fit at the chest, waist, and limbs, and use the brand’s size chart for guidance. If you’re between sizes, choose the larger for comfort. 

Most wetsuits are made from neoprene, a synthetic rubber that provides insulation and flexibility. Some modern wetsuits use limestone-based neoprene, which is more flexible and environmentally friendly than traditional petroleum-based neoprene. 

For water above 20°C, a 2mm shorty is suitable. In 14–18°C, opt for a 3/2mm suit. For colder water (10–14°C), use a 4/3mm, and for temperatures below 10°C, choose a 5/4mm or thicker, possibly with a hood, gloves, and booties for extra warmth.
