CHECK THE SIZE CHART (in the image section above) The men's Jaked Shockwave Multi-Thickness long-sleeved wetsuit is a great choice for aspiring triathletes and open water swimmers. Thanks to the Fine Mesh finishing, the surface of the neoprene is rough and micro-perforated, this allows it to retain the water molecules which boosts the sliding effect of the suit (AcquasuAcqua). Made with Yamamoto neoprene with high performance cells that provide enhanced buoyancy, high heat retention and minimum hydrodynamic resistance. Jaked wetsuits have been developed together with Salvimar, an Italian leading company in water sports equipment. Features: 100% Yamamoto neoprene, a premium quality material providing high durability, enhanced comfort and constant elasticity. 4.0 mm high density neoprene on the core area of the body, to guarantee heat insulation, best compression and high durability. 0.5 mm neoprene on shoulders, armpits, forearms and lower legs, for maximum elasticity of movement and quick removal. 4.8 mm closed-cell neoprene, highly compressive on thighs to increase buoyancy. Watertight raw edges on wrists, ankles and neckline, for a quick and easy removal. Jersey Stretch inside lining to make the wetsuit easier to wear. JP heat tape system on the inside for a total waterproof sealing. Professional zipper with salt resistant metal slider 90% Neoprene 10% Nylon
