The Heptagon is a 7mm full one-piece wetsuit designed with Cressi?s NeoPro-fit design to ensure maximum comfort. NeoPro-fit combines superior erosion resistance and durability with elasticity and softness, while providing performance and affordability. The Heptagon's ergonomic cuts provide ease of donning and doffing and allow complete and effortless movement while in the water. The wetsuit features high-quality Ultraspan? neoprene that provides comfort and longevity. The knees are reinforced to protect the wetsuit against scratches. The wetsuit collar is anatomically designed to prevent constriction and features a Velcro? closure. The back closure is fitted with a metal YKK? zipper and a flap that prevents water from entering. The Heptagon?s 7mm thickness guarantees heat retention for long dives in colder water, for both scuba diving and snorkeling.
