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 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. New L. I. F. T. panels on the back of the legs keep you in an efficient downhill swimming position to help increase speed while reducing effort and fatigue. Ultra-buoyant Yamamoto neoprene keeps you warm in chilly waters while adding float for superior swimming efficiency. All that buoyancy amounts to nothing if your flexibility is inhibited by unforgiving neoprene, so the Helix incorporated an improved version of Blueseventy's venerable Torsional Stretch Technology (TST). In a TST fullsuit, the chest and back panels allow the arm and shoulder to "disconnect" from the suit, freeing the deltoids for an uninhibited stroke. Blueseventy placed thinner, less buoyant 3mm Body Fit panels at the sides to allow more natural hip rotation and easier suit removal, and the VO2 chest split construction allows the suit to flex with your lungs' expansion during hard efforts, so the snug fit doesn't come at the cost of limited lung capacity. Your arms enjoy similarly unencumbered movement, with the underarm gussets of 1mm neoprene extending to the wrists for unrivaled flexibility and freedom of movement. They terminate in a silicone cuff for a perfect seal against flushing. The forearms have inserts of Aqua-Feel catch panels, which help dial-in you...
