We developed this jersey for the pro riders for racing in the heat and mountains of the tour de france we were surprised when we put it in the wind tunnel and found that it was the most aero jersey we had ever tested then we noticed the pro riders using it on cool and wet days because it dries so fast its really the ideal jersey for every condition its also one of our favorites for long hot climbs in the dolomites features drypro lite for instant drying excellent stretch yet goo
