Nikki van Dijk Wetsuit (3/2) ― Moon

A full wetsuit covers your entire body for extra warmth and insulation—ideal for colder waters—while a spring suit offers protection for the torso and limbs, providing more flexibility for warmer conditions. Choosing between them depends on your typical water temperature and activity level.

Wetsuits are typically designed with specific water temperatures in mind. Lighter spring suits work well in warmer conditions, while full-length, thicker suits offer more insulation for colder waters. However, many modern wetsuits provide versatile performance across multiple seasons if chosen correctly for your local climate.

Wetsuit thickness generally varies by water temperature:
• Warm water (above 24°C/75°F): 2-3mm suits are typically sufficient.
• Temperate water (18-24°C/65-75°F): A 3/2mm suit provides a balance of insulation and flexibility.
• Cold water (below 18°C/65°F): 4/3mm or 5/4mm suits offer enhanced thermal protection.,
Always refer to sizing guides and manufacturer recommendations to find the best option for your local conditions. For more information, visit our blog.

To extend the life of your wetsuit, rinse it with fresh water after every use, hang it to dry in a shaded, well-ventilated area, and avoid prolonged exposure to direct sunlight. Using a specialized wetsuit cleaner will help maintain its performance and durability over time. for more information, visit our blog.

A wetsuit is engineered primarily to keep you warm by trapping a thin layer of water between your skin and the suit, which your body heat then warms. While they aren’t completely waterproof in the traditional sense, they’re designed to reduce heat loss and keep you comfortable in the water.

While wetsuits do provide a small amount of buoyancy due to the neoprene material, they are not designed to replace life jackets. Their primary function is thermal insulation and flexibility rather than flotation support.

For open water or outdoor swimming, choose a wetsuit that offers a snug, hydrodynamic fit, quick-drying materials, and full coverage to maintain warmth. Wallien’s wetsuits are engineered with features like UV protection, chlorine resistance, and ergonomic design to provide the perfect blend of mobility and insulation.

Wetsuits provide critical thermal insulation, reduce the risk of abrasions, and offer buoyancy, which enhances your comfort and performance while surfing. They protect you from cold water, sun exposure, and potential injuries from your board and other equipment.

Yes, many wetsuits are versatile enough for swimming, surfing, kayaking, kite surfing, and paddle boarding. Choose a suit that aligns with your primary activity—such as a streamlined model for triathlons or a more robust design for surfing, to ensure optimal performance across various water sports.
