Mavic's Helium Bib Shorts feel as fabulous as they function thanks to Mavic's lightweight Sleek Power fabric that transfers moisture and breathes to keep you dry and comfortable. You also get Mavic's protective, supportive Ergo 3D Pro chamois and their Hot Ride + technology mesh panels to prevent overheating. You'll love the wonderful freedom of movement from the bibs and the chafe-free external leg grippers that keep these shorts in place.
