Tests de Loughborough

Independent testing at Loughborough University, one of the world's leading centres for human performance, evaluated how Zone3 wetsuits influence speed, efficiency and physiological load across different athlete levels. This collection gathers the wetsuits behind that testing.

The tested range spans the tiers: the Vanquish-X, the pinnacle of Zone3 wetsuit development for athletes who demand more from every stroke; the Vision, named Best Triathlon Wetsuit of 2024 by Triathlete.com and made with 100% B-Prene Yamamoto neoprene; and the Agile, whose two, three and four millimetre buoyancy panels keep newer swimmers streamlined and reduce fatigue.

Testing across athlete levels matters because wetsuit benefits differ with experience: the suit that helps an elite athlete hold speed is not automatically the suit that helps a first-timer swim further with less effort. Evidence from a leading sports science institution sits behind the range, so you can choose a wetsuit on measured performance rather than marketing claims.
