The Bern Women's Brighton EPS Thin Shell Helmet is here to help your head whether you're skiing down Pioneer Peak or mountain biking the Lakes Loop. Certified for both sports, the Brighton uses a thin ABS shell that feels good in summer and winter, and you can switch out the included EPS Winter Liner for Bern's EPS Summer Comfort Liner. Boa's adjustable dial ensures a secure, wraparound fit. There are slots inside each ear pad for audio compatibility.
