The Free Aero Race has been Castelli’s No. 1 selling short for the past few years, and the outgoing version essentially ran from 2007 to 2014 with a few minor face-lifts. For 2015 every single detail in the Free Aero Race has been improved. At first look the lines are classic Free, but in fact only the mesh fabric in the bib straps carries over from last year. Every other component and detail has been redesigned, obsessed over and tested until Castelli were satisfied.
