The Gold Cell is a high end model with high performance capability that will keep you warmer. This model is made with the Metal Cell technology with neoprene on the outside and inside, treated with SCS to make it very slick when in direct contact with the skin and the water. The end result is that the neoprene stays very close to the skin and allows virtually no water into the suit. Thereby, your body has to heat less water, keeping you warmer. The suit is made with two layers of GIGA #40 from Yamamoto giving it a very good quality/price ratio. This model is a perfect suit for a triathlete who is looking for performance and warmth. You will love the flexibility, comfort, lightweight feel, fast removal, and warmth in cold water . The shoulders of the Cell Gold are made of GIGA #40 to allow maximum flexibility for totally free movement. The forearms have the “Aero Design Propeller” to provide a better catch of the water during the pulling phase of the stroke. The collar, made of GIGA #40 has a new “Revolving Collar” which positions the front of the collar forward by 20 degrees and is 2cm lower allowing for more comfort and reducing the entry of water through the collar area.
