Castelli T1Stealth 2 Jersey Men's

Shaving precious time from the bike leg of triathlon races, the Castelli Men's T1:Stealth 2 Jersey is wind tunnel tested for absolute streamlined efficiency. Castelli claims it shaves an astonishing six minutes from the bike leg of the world's most iconic triathlon hint: it's based in Hawaii, compared to its sleeveless Free top. This second generation version sports updated pockets and a flatter waistband, both of which increase aerodynamics while improving convenience for grabbing water bottles and energy supplements.
