Look good, feel good. It's as simple as that. Beneath the shapely exterior of the Bell Women's Tempo Joy Ride MIPS Bike Helmet, you'll find useful features to keep you cool and comfortable on rides of any distance. The ErgoDial fit system offers simple, one-handed adjustment for a precise fit. The large open vents channel in cool air. The high-quality, lightweight construction makes it feel like it's barely even there. And you get the option of MIPS (Multi-Directional Impact Protection System), which can provide an additional measure of protection in certain impacts.
