The Baker EPS Visor Thin Shell Helmet is Bern's original brain bucket, now certified for mountain biking as well as skiing. The thin ABS shell feels light for summer weather, and EPS foam protects your dome from hardpack and rocky terrain. Boa's adjustable dial ensures a fully secured, wraparound fit. There are slots in both ear pads for audio compatibility, and a goggle attachment for straps. This helmet comes with an interchangeable EPS Winter Liner that you can switch out for an EPS Summer Liner.
