Great style meets cool comfort. The Coast features an adaptable design that's an easy match with what you wear and how you ride. This model features MIPS (Multi-Directional Impact Protection System) which can provide an additional measure of protection in certain impacts. Large air vents keep you cool, and a quality polycarbonate shell gives it a lightweight feel. The one-size-fits-all Ergo Fit system offers a slimmed-down, easy-to-use dial, plus this year No-Twist Tri-Glides have been adopted for added ease of adjustment.
