Sharkskin Chillproof Back Zip Suit - Mens
The Sharkskin Chillproof Back Zip Suit represents a high-performance evolution in thermal protection gear, offering advanced insulation, breathability, and flexibility for water sports enthusiasts and professional divers. Engineered by Sharkskin USA, this full-body suit incorporates a unique three-layer fabric technology known as Chillproof, which mimics the thermal properties of a traditional 2.5 to 3 mm neoprene wetsuit, while providing superior comfort, reduced buoyancy, and advanced environmental protection.
Designed for a wide range of aquatic activities—scuba diving, snorkeling, paddleboarding, kayaking, surfing, and open-water swimming—the sharkskin wetsuit offers both standalone performance in moderate to warm waters and layering compatibility under a traditional wetsuit in colder conditions. The Chillproof material is windproof, breathable, and quick-drying, addressing many of the pain points users experience with standard neoprene suits, such as overheating on the surface or feeling clammy post-dive
Where conventional wetsuits may trap sweat and limit freedom of movement, this sharkskin wetsuit excels due to its internal hollow-fiber fleece lining, which actively wicks moisture away from the body while retaining core warmth. This is particularly beneficial during surface intervals or prolonged paddling when wind exposure can rapidly lower body temperature. The middle membrane is windproof and breathable, which allows excess heat and moisture to escape, helping the user maintain a more stable internal temperature. Meanwhile, the external layer is abrasion-resistant, saltwater-tolerant, and UV-protective, ensuring long-term durability even with heavy use in salt and sun-rich environments.
Unlike neoprene suits, which require additional weights due to their inherent buoyancy, the Sharkskin Chillproof suit is neutrally buoyant. This reduces diver fatigue, simplifies buoyancy control, and makes it an ideal garment for both beginners and seasoned water athletes. Since the suit adds minimal weight and bulk, it’s also easier to pack for travel, making it a popular choice among mobile adventure divers and expedition paddlers.
The inclusion of a back zip entry provides a secure and comfortable fit, while maintaining ease of donning and doffing the suit without assistance. The rear zipper extends vertically along the spine and is secured with a robust zipper closure system that resists wear and corrosion from repeated saltwater exposure. Reinforced stitching with durable thread—specifically chosen for its saltwater resistance—ensures long-lasting integrity, even under high-use scenarios.
