Full-Wrap Liner This full-coverage, washable liner snugly cradles your head, creating the unmatched fit of a K2 helmet. The liner features a crown mesh that wicks moisture and breathes to prevent overheating. There are no gaps, which means a better fit and improved comfort.
K2 Level 3 Baseline Audio The K2 Level 3 Baseline Audio system seamlessly connects you with your cell phone or media player. The audio system comes pre-installed in Baseline Audio Earpads. The speaker housing creates a minimal, low-profile stowage so you won't notice the speakers unless the music is playing. If you would rather ride without the speakers installed, they can be easily removed from the earpads with a detachable cord and an all-new on-cord audio controller for initiating the on-the-go pause/play and answer/hang-up functions, your media device is literally at your fingertips.
