Castelli T1 Stealth Top – Men
The draw: Faster bike splits
Finally, the drag-saving technology that has long been available to cyclists has made its way into triathlon. The T1 Stealth is meant to be worn on the bike and then removed in T2 before starting the run. Castelli claims the top will save roughly three minutes over an Ironman for an athlete splitting 5:00 on the bike. Other than its aero benefits, it also provides protection from the sun by covering the shoulders and upper arms. Be sure to buy the size that fits you snugly to maximize the top’s aero properties.
