Available in two sizes for a tailored women's fit, Quantum WSD features great ventilation, excellent coverage, and of course Bontrager's signature out-of-the-box comfort and incredible ease-of-use. A removable visor adds to the value of a helmet that feels just as at home on the trail as it does on the road.
