Shred Optics' Half Brain Helmet is a smart choice for snowboarders with at least half, no, a quarter of a brain. This brain bucket meets the most essential safety certifications, and it exceeds expectations in terms of comfort. The Fit Perfect Finder uses three straps one on top and one on each side and a ShredWheel dial for a secure customized fit. ShredVent uses a lot of vents to promote airflow and prevent fogging, and the foldable vent cap closes and opens each vent for further customization. The cushy lining is removable for easy cleaning.
