A step above the 2XU T:3, the R:3 Wetsuit features the same Yamamoto neoprene, fit to swim cut, and technology designed to position you higher in the water for a more optimal swim stroke. What sets it apart are a few key details that help to optimize the effectiveness of your stroke, making it an even faster wetsuit. Yamamoto neoprene is known for its flexibility, and the R:3 has been entirely constructed using SCS coated Yamamoto neoprene in welded panels. And while the neoprene is itself buoyant, 2XU added proprietary features that enhance body positioning in the water. The most noticeable is a 39 Cell Front Buoyancy Panel. This helps to elevate the body in the water, which, in turn, assists in stroke mechanics. Additionally, Velocity Strakes placed on the chest streamline tracking through the water. The shoulder and arm panels are seamless and were constructed from thinner, 1. 5mm, neoprene. This allows for even greater movement and flexibility during all phases of the swim stroke. The added Rollbar technology works to keep the core tight and the body properly positioned to maximize efficiency in the water. Added features include Concave Water Entrapment Zones CWEZ on the forearms, which work to increase the strength of the pull phase of the stroke, as well as a flexible, floating zip panel that increases flexibility in the reach phase of the stroke. The lining of the wetsuit is able to stretch 520% to ensure a flexible and custom form fit. The R:3 wetsuit is, of course, a form fit suit. It features a full length rear zip with extended strap so that you'll be able to quickly grab it while running into T1. The suit secures at the neck with a wide hook and loop panel. It comes with a 2 year warranty. The 2XU R:3 Race Wetsuit Women's is available in sizes X Small, Small, Smallmedium, Medium, Large, and X Large. It comes in the color Blackblue.
