The culmination of years of testing and research, the Helix Fullsuit introduces Blueseventy's TST (torsional stretch technology), a remarkable innovation in trisuit design that isolates the shoulder panels from the body of the suit to radically improve arm-stroke flexibility. Combined with the quick-exit legs, reverse zipper and multi-stretch cuffs, the helix improvements make for a faster and more comfortable suit in every way.
