Bern built the Women's Lenox EPS Thin Shell Visor Helmet with a lighter feel, and it still takes the impact on all your brain-busting activities. Certified for mountain biking and snowboarding, the Lenox uses a thin ABS shell that feels right for summer or winter weather, and you can switch out the included EPS Winter Liner with an EPS Summer Liner for customized comfort.
