Performance. Backed by evidence

Independent testing at Loughborough Sport evaluated three athletes — beginner, intermediate, and advanced — across four 750 m swims each, with and without Zone3 wetsuits.

Averaged results demonstrated measurable improvements in efficiency, speed, and physiological response across all suits, with outcomes varying by individual.
