Zone3 collaborated with Loughborough Sport to independently evaluate how wetsuit design impacts triathlon swimming performance.
Three athletes of different experience levels completed four controlled 750 m swims:
one without a wetsuit, then in the Agile (entry-level), Vision (mid-level), and Vanquish-X (elite).
AGILE ENTRY LEVEL WETSUIT
Proven performance. Confidence from the first stroke.
Independent testing at Loughborough University assessed how different wetsuit designs influence swim performance.
Across a case study of three athletes — beginner, intermediate, and advanced — the Agile demonstrated measurable gains in speed and efficiency at the same perceived effort.
AGILE KEY FINDINGS
As the entry-level suit in the Zone3 range, the Agile improved body position and reduced drag — helping swimmers move more efficiently through the water. The results, averaged across three athletes, show clear performance benefits at a consistent effort level.
Confidence. Comfort. Proven performance
