The Macon Team edition offers fully upholstered interior for a performance fit over your favorite beanie. It also dishes up core clean lines that will look good during any season. Dishing out comfort & safety the Macon has a few different constructions that are sure to meet your needs whether you’re on your board, bike, the slopes, or in the water.

Depending on the season your helmet will come with either an EPS Summer Comfort Liner or an EPS Winter Liner & you can buy the alternating season’s liner based on your needs to keep up with you through the seasons.
