The Gold Cell is a high end model with high performance capability and will keep you warmer. This model is made with the Metal Cell technology, which is 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. This, in turn, forces your body to heat less water, thereby keeping you warmer
