From summer singletrack rides to indoor training sessions, the POC MTB Air Layer Bib Short tag along on all of your rides with exceptionally lightweight, breathable comfort. Focusing on ventilation, a very lightweight mesh material is used over the entire bib shorts, making them an ideal fit under typical trail clothing, while the VPDS Catalyst pad uses VPDS silicone inserts for extra comfort and vibration absorption, not to mention a bacteriostatic fabric for lasting freshness. Plus, you get even more ventilation from the perforated elastic on the leg grippers that hold everything snugly in place.
