Designed as a certified all season helmet, the Bern Macon EPS Helmet is equally skilled at protecting your brain from bike , skate , and snowboard related impacts. Its thin ABS shell is lined with EPS foam for high levels of impact protection cracking to disperse the blow of serious spills regardless of whether you're falling onto dirt, concrete, or snow. Passive ventilation ports keep your head nice and cool when you're working up a sweat on hot summer days. Note that this helmet comes with an EPS Summer Comfort Liner for bike and board use in warmer conditions. The EPS Winter Liner is sold separately, allowing you to convert this brain bucket into a certified winter helmet for use on the slopes.
