Why the T1 Wetsuit is better than any one-piece wetsuit:
The two-piece design of the T1 wetsuits offer more comfort and less restriction. Because the top and bottom are not attached, changing your stroke is not necessary. There is no “torso-rubber stretch” or shoulder fatigue that occurs with all one-piece wetsuits. All T1 models are sold as separates "modules" for a more customized and personal fit.
Because the tops and bottoms are sold separates, there are up to 49 different combinations from which to create your personal fit. If you mix the combination of tops and bottoms with all the possible sizes, there are over 500 combinations. For this reason, there is no need to offer different men's sizing and women's sizing.
