2XU MEN'S TRIATHLON
Life is a series of choices, and in triathlon, you either choose to go slow or to go fast. We choose the latter. However, this choice is hinged on utilizing the right gear. And in the world of water, the buoyancy of the 2XU R:2 Race Wetsuit provides the key element for speed.
The path to speed takes many forms, and accordingly, the path to a faster wetsuit requires many engineering features. So, 2XU approached the R: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 R: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-density, raised surfaces 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.
Surely, the aforementioned engineered system of position control sounds right on paper, but you're probably wondering what its real-world application is? Well, aside from proprioceptive dynamics, it also brings us to our next subject, hydrodynamics. Basically, the R:2's goal is to make you faster in the water. And just how curvy, sleek shapes minimize your drag coefficient on land, the wetsuit's level of buoyancy is the minimizing variable in the water. The supporting science behind this claim is fairly elementary -- water is around 1000 times denser than air, and it produces a potential drag coefficient 10 times that of air, as well. So, minimizing your body's submergence is vital to optimizing hydrodynamics. Accordingly, the R:2 features a variable-density neoprene with a 5mm front buoyancy panel.
Additionally, the R:2 benefits from a hydrodynamic, silicone SGS/Silicone Hydro coating that provides an added level of buoyancy, while lowering the suit's coefficient of kinetic friction. Without entering into a physics lesson, the coefficient of kinetic friction is most simply described as the ratio of the force of friction between two bodies, and the force pressing them together. And in this case, the two bodies are your body and the water and friction occurs concurrently with their motions. So, in the real-world, SGS acts almost like an accelerant as it reduces the friction between yourself and the water, ultimately requiring you to exert less force in order to gain more speed.
So, we've discerned how the R:2 design assists in conserving your energy by lowering your required output of force. But, the V:2 also has features that maximize the force that you apply. For example, 2XU equipped the forearms and lower legs with its catch panels. These sections of the suit provide the appendages with a drastically increased surface area. So, with the panels, more water is displaced during your catch and kick phase. Accordingly, your propulsion through the water is maximized with less required force.
For flexibility, the R:2's neoprene is not only buoyant, but it also features one of the most flexible rubber compositions on the market -- 520%, four-way stretch. Additionally, the suit varies its density down to a malleable 1.5mm at the underarms and shoulder panels. It also has a floating back panel that's non-restrictive nature allows more air into the chest cavity. This concept is furthered by the suit's seamless, floating zip panel. So, your reach is extended, while abrasion is eliminated.
The 2XU R:2 Race Wetsuit is available in the color Black and in six sizes from X-Small to XX-Large, with Small/tall, Small/medium, Medium/tall, Medium/solid, and Large/tall options also available.
