Sharkskin Chillproof Men's Chest Zip Long Sleeve Top Black 5X-Large

Adjustable Warmth for Changing Conditions
The Sharkskin Chillproof Chest Zip Long Sleeve Top is designed to adapt to varying activity levels and weather conditions. The chest zip closure allows you to fully seal the top for maximum warmth and protection, or partially open it when the sun appears or exertion increases. A long sleeve design provides full upper body coverage, while the high collar helps retain warmth around the neck. This makes it well suited for paddle sports and power watersports such as jet skiing where both protection and ventilation control are important.

Chillproof 3 Layer Thermal Construction
Made from Chillproof, an aquatic specific 3 layer composite material, this men's thermal dive top offers thermal properties similar to a 2.5 to 3mm neoprene wetsuit without many of the traditional drawbacks. The nylon and spandex outer layer provides durability and abrasion resistance. A 100% windproof 10K+ breathable membrane blocks windchill while allowing heat and moisture to regulate. The inner hollow fiber fleece layer sits next to the skin to enhance warmth, comfort, and moisture wicking.

Comfort, Protection and Durability
A durable water repellent finish helps shed water, forming a protective outer shell. 4 way stretch construction ensures unrestricted movement and makes the garment easy to put on and remove. Non chafing, itch resistant and odor resistant properties support extended wear. Seam threads are selected to resist deterioration in saltwater, contributing to long term durability. The top is neutrally buoyant, so no additional dive weight is required. UPF50+ protection adds reliable sun coverage during prolonged exposure.

Versatile Use Across Water Sports
This men's water sports thermal layer can be worn on its own as thermal protection or layered under a wetsuit for additional warmth and wind resistance. It is suitable for scuba diving, snorkeling, jet skiing, paddle sports, board sports, wind sports, sailing, and other marine activities. Designed with advanced materials and quality manufacturing techniques, the garment focuses on lasting performance while maintaining consideration for environmental impact in its production approach.
