Let"s face it, a triathlon wetsuit brings more to the table than just added warmth in the water. In fact, we argue that, come race day, the energy-saving effects of hydrodynamics, buoyancy, and propulsion far outweigh the importance of temperature regulation. However, while many lay claim to the aforementioned characteristics, seldom will you see the engineering that supports these claims. That is, until 2XU launched its Project X wetsuits in 2010. And as the second iteration of this ground-breaking line, the X:2 Project X Wetsuit advances past technologies into race-ready wetsuits for today"s level of competition. The path to speed takes many forms, and accordingly, the path to a faster wetsuit requires many engineering features. So, 2XU approached the X:2 with a four-part ideology -- body position, flexibility hydrodynamics, and buoyancy. Coincidentally, much of 2XU"s engineering towards body position also aids in buoyancy. And accordingly, the X:2 ensures an efficient body position through the development and implementation of its velocity strakes and rollbar technologies. Basically, the velocity strakes are strategically placed and angled points of 5mm raised surface that run from the neck to the knee. These strakes perform many functions, but one of their more notable applications is improving posture in the water, or more precisely put, they efficiently channel water along the body in order to increase your stability and flow. This results in less sideways movement in choppy conditions, and also, it provides an enhanced lift to the body in glassy waters. The rollbars that run along the sides from the hip to the top of scapula operate with the same principle -- minimizing the shoulder and lats tendency to sink inwards during the locomotion of your stroke.
