  1. Cheryl

    The most comfortable helmet I’ve ever worn! The wider brim offers ample sun protection without being unwieldy and ugly like some brims. The washable liner is great to keep it it clean and avoid forehead breakouts. I wouldn’t trust my head to anything but a One K!

  2. Kelsey

    I’m absolutely in love with my new OneK defender AVANCE wide brim I just got.
    I’ve been a die hard GPA lover for ten years and this helmet surpasses any expectation I ever had! My head is not drenched in sweat when I take off my helmet after my ride because the amazing ventilation it has, the shape is very complimentary to my head, they also make different shapes to make it easy for riders that are hard to fit.
    I’m now a diehard OneK fan!

  3. Susie Lynn

    It too me FOREVER to find a wide brim helmet that doesn’t swallow my face (adult with an XS size head- the struggle is real!) This is that helmet. The long oval shape fits perfectly, is super comfy, has good airflow, and I get so many compliments on the navy color. One K convert for life!
