The Schwinn Starlet Wave bike helmet offers a lightweight comfort and protection with an aerodynamic design for women riders. The Starlet Wave is offered at a budget-friendly price-point, yet offers advanced features typically reserved for pricier helmets. First and foremost, the helmet provides the custom fit you need for comfort and safety with the Dial Fit system. This system allows you to tension the helmet for an exact fit by turning a dial at the back of the helmet. This eliminates the need for the extra foam spacer cushions common to inexpensive bike helmets, which also can compress and compromise the fit over time. The Dial Fit system also makes it easy to adjust the under-chin strap which features soft, dual-stitch straps for increased comfort. Designed to keep you cool and air circulating especially in hot weather, the Starlet Wave features 21 contoured air vents with exhaust ports that bring cool air in and force hot air out. Finally, the helmet is equipped with an optional snap on/off visor to keep the sun off your face and out of your eyes.
