The 2XU A:1 Active Wetsuit falls near the lower price point of its wetsuits, yet it is designed with all the features of suits that cost twice as much. Top-tier neoprene and an array of body positioning panels create a fast suit for an optimal swim. Yamamoto neoprene is known for its flexibility, and the A:1 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 Rollbar technology also 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 A:1 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 A:1 Active Wetsuit - Women's is available in sizes X-Small, Small, Small-Medium, Medium, Large, and X-Large. It comes in the color Black/ultraviolet.
