Castelli custom clothing

Developed with the pros

true

Castelli is dedicated to making the best custom clothing in the world. 

We do the basic research, then we test the concepts internally, then we test them with the Quick-Step Alpha Vinyl Team or with our professional triathletes.

Only then are they available in Castelli’s custom program.

On winning her biggest race

" It was a hot and humid day out there, and not once in 200 miles did I have to think about what I was wearing. The ease of a skin suit, with no shoulder straps or constricting around the middle, kept my shoulders and my stomach happy. And I was back on the bike two days later, which speaks to the quality of the chamois :) "
