Channeling two decades of experience designing the world's best wetsuits for serious triathletes and Olympians, the Blueseventy Women's Helix Full Wetsuit takes obsessive performance to new heights, delivering outstanding buoyancy, unparalleled upper body flexibility, and fluid stroke movements. That being said, it's best suited for expert triathletes looking to maximize their speed in the water. In fact, with the exception of the ultra thin Honeycomb Aqua Feel forearm panels that increase arm awareness and positioning, the Helix doesn't focus on enhancing preprioception. Instead, it primarily targets boosting buoyancy and flexibility, which are the most important features in maximizing speed and subsequently shaving time off your swim stage. Designed around a 5 5 4 buoyancy pattern, the Helix raises your hips in the water, courtesy of its torso and VO2 Chest panels with 5 millimeter Yamamoto neoprene. This allows you to swim in a downhill manner, propelling yourself forward and out of the water. The chest's split construction and anatomical design maximize stretch during respiration. Thinner neoprene along the arms and lower legs gives you the full range of motion needed for powerful strokes and forward propulsion. Throw in Blueseventy's signature Torsional Stretch Technology distinctive blue panels to eliminate seams and free up the deltoid muscles for extra mobility throughout your stroke. Quick transitions are essential to efficiently moving through to the bike stage. Realizing this, the Helix features Quick Exit legs with 2 millimeter lower leg panels for efficient removal, as well as flared ankles to keep your feet from catching. Furthermore, there's a reverse zipper design that's fast to remove and extremely comfortable to wear, without the bulky zipper head plaguing you behind the neck.
