    What is WaveCel?

    WaveCel is a revolutionary helmet technology designed to be more effective than traditional foam helmets in protecting against certain cycling-related accidents.

    Easily secure and adjust the helmet fit with just one hand.

    Soft Helmet Pads

    Super comfortable internal pads wick moisture on hot days and hard efforts and are easy to wash after a full day of fun.

    FlatStrapSemi-Fixed Dividers

    Comfortable, lightweight semi-fixed strap dividers fit flat to your face on a single strap and move fore and aft to get into an ideal position under your chin.

    Blendr Front & Rear Magnetic Mounts

    Seamlessly-integrated accessory mounts for GoPro and Bontrager Daytime Running Lights so you decide when you want them.
