A 4mm kids wetsuit is designed for colder water conditions, typically ranging from 50°F to 60°F (10°C to 15°C). Made from high-quality neoprene, it provides excellent insulation, keeping the body warm while still offering flexibility for active water sports like surfing, diving, paddleboarding, and kiteboarding. The 4mm thickness ensures greater thermal protection, making it perfect for extended sessions in cool to cold waters. This wetsuit strikes a great balance between warmth and mobility, with features like reinforced knee panels for durability, flatlock seams to minimize chafing, and a snug fit to prevent water from flushing in. Ideal for those who need extra warmth without sacrificing movement, a 4mm wetsuit is a solid choice for colder water activities, offering both comfort and performance!
