The two-piece design of the De Soto Wetsuits offer more comfort and less restriction. Because the Wetsuit Tops and Wetsuit Pants are not attached, changing your stroke is not necessary. There is no “torso-rubber stretch” or shoulder fatigue that occurs with all one-piece Triathlon Wetsuits. All T1 models are sold as separates for a more customized and personal fit. Improvements made over the past couple seasons include new graphics, elliptical leg openings, lower profile and more durable bibstraps, and more buoyant zippers.
