We currently have/use 5mm gold core. Is the 5MM hyperstretch 100% equivilent in warmth?
LeisurePro S The hyperstretch suits, while much stretchier that the cold core, aren't going to be quite as warm. The difference will be small, but the gold core suits have more insulation power to them because of the way they seal to the body. The hyperstretch will provide the warmth equivalent to a traditional neoprene suit.
