Premium Performance. Minus a Premium Price. Bringing together as much technology as possible from their premium cycling shorts, but without the premium cost, the Competizione Kit Cycling Bib Shorts are perfectly at home in the cut and thrust of a race but also brilliantly comfortable for all those times when you're not pining a number on. From their Free Aero Race 4 shorts come both the low-drag Vortex BLC textured fabric on the legs and the Giro4 leg grippers, complete with a raw-edge finish for a wonderfully smooth and comfortable fit and slippery aerodynamics. Mesh straps to the bib section guarantee excellent breathability and flatlock stitching ensure chafing is a thing of the past. Not only benefitting from Castelli's fabric know-how, but the Competizione also get a signature Castelli fit. Supportive of your muscles and with the perfect degree of flexibility, they're ever so comfortable from the moment you pull them on. The cost to performance ratio is simply unbeatable. KISS Air2 Seat Pad When you're on the bike you'll also enjoy superb on-the-saddle comfort from Castelli's KISS Air2 seat pad. Next to the skin, you'll enjoy the luxury of Castelli's softest ever surface fabric, delivering immediate comfort. Seamless construction and stretch fit all but eliminate chafing as you push the watts. Next comes the dual-density, variable thickness padding. This sees maximum density and thickness across the ischial zone, reduced thickness around the perineum and then minimum thickness at the edges. This is all wrapped up in an anatomically shaped pad for optimal comfort for any distance.
