Rip Curl Men\'s Performance 5/3mm Wetsuit The Rip Curl Performance 5/3mm chest zip wetsuit for Men is a winter suit designed for those that want maximum movement in the water as the Neoprene used is all super stretch. This means that when you move the suit moves with you and in the winter months this is a big bonus as you get a better fit which will keep you warmer for longer. Being a 5mm wetsuit means that it is designed to be used in the coldest winter months such as December to April in UK waters.
