This Men's Tri Tank features Carbon Technology and those in Carbon jerseys showed fluctuation in body temperature three times lower than when wearing polyester jerseys. This is due to the Carbon's capacity to promote perspiration along with significantly faster evaporation rates. Athletes also exhibited rates four heartbeats per minute lower than those wearing polyester and they showed an approximate 12% decrease in lactic acid concentration in capillary blood. The conductive material's continuous filament guarantees effectiveness, even after many washes.
