The culmination of years of testing and research, the Helix suit 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 2007 this was the suit of choice for athletes in the pro ranks, and based on their feedback,
blueseventy has added enhancements that will help perpetuate that perception.
TST (torsional stretch technology) mechanically decouples the arms from the rest of the suit
Larger underarm gusset anatomically aligned for better movement
Thinner 1.5 mm arms with a more malleable jersey improves flexibility
Swim cuffs feature internal silicone print to reduce water entry and reduce movement of the cuff against the skin
Ribbed rubber behind the knee reduces compression resistance during knee flexion when running
Reduction in collar bulk to reduce abrasion and assist in sighting
Anatomically designed back and shoulder panels allow maximal stretch in all directions
Reversed Quick Exit Zip
Anatomical lower leg cut, including high stretch inserts
Pre-formed elbows and knees reduce resistance through the water
