Santini Audax triathlon sleeveless body

All About Performance

Audax tri suits and two-piece kits are made with the ultimate combination of performance fabrics and construction methods. We use lightweight, aerodynamic and UV resistant Clima shuttle-woven fabric in the uppers. The lowers are made from Fitter, a compressive and abrasion-resistant fabric that both reduces muscle stress and lowers the risk of chafing. And we build them all around a brand new chamois called IMG (IRONMAN Gel) that is super-thin, fast-drying, and has a silicone-gel core seat pad.

IMG chamois
IMG is a triathlon specific chamois ideal for long distance races. The IMG weighs only 52 grams and features the new innovative patented Tower Gel core by Nicolini which is 40% lighter, doesn’t absorb water, and is 60% more flexible than the gel core of our cycling bib-shorts. The structure of this gel is made of small “towers” which are bigger in the ischiatic area and diminish in size towards the edges of the seat pad, offering a high level of shock absorption for up to 7 hours in the saddle. The “tower structure” also enhances the breathability of the padding by 45%, and thanks to its flexibility it adapts perfectly to the body throughout the swim and the run.

Sleek Fit
Skintight fit, developed with riding position in mind to maximize aerodynamic properties.
