That this bibshort improves the performance is not our opinion but the result of hundreds of tests in the wind tunnel. Fast Bib Shorts uses a
specific fabric from the Kinetech® DRAGZERO range which thanks to its structure helps to reduce the drag coefficient. Beside the highest technology available in fabrics, we have used the highest technologies in assembling it, such as ultrasonic bonding instead of stitching and bonded borders. At the legs’ hem a special fabric will surprise you further: a silicone-free thin band which is soft like silk but grips like rubber.
