We constructed the shape of our wetsuit based on swimmers with their arms up, as well as one arm up at a time, instead of standing with their arms at their side. We then created our own algorithms for optimal comfort, performance, fit, and sizing. Algorithms were based on measured dimensions on over 60 locations on the body. Since our two-piece concept already allows for more shoulder freedom than any one-piece wetsuit, the optimal result was to create a pullover based on arms up and forward. This is how we developed what we still call to this day, the Bio Stroke™ Design.
We quickly learned we needed to either eliminate the zipper, or create a way where the zipper does not hinder flexibility of a one-piece wetsuit to overcome the limited range of motion and discomfort. Any one-piece wetsuit manufacturer on the market has still not accomplished this today. The logic behind our two-piece design still remains true.
Because the top and bottom are not attached, the T1 Wetsuit will not force you to change or limit your stroke. There is no “torso-rubber stretch” or shoulder fatigue that occurs with one-piece wetsuits. All T1 models are sold as separates "modules" for a more customized and personal fit.
