One K MIPS CCS Helmet

The One K Defender MIPS helmet combines trusted protection with advanced rotational impact technology. MIPS—developed by Swedish neurosurgeons and engineers—redirects angled impact forces away from the brain, independently proven to reduce rotational motion during falls. Built with a durable polycarbonate and ABS composite shell, this helmet features strategic ventilation across five ports to keep you cool during intense rides. The quick-dry, moisture-wicking liner resists odor and bacteria, while the padded harness with synthetic suede and adjustable hook-and-loop closure ensures a secure, comfortable fit every time. Easy maintenance means a quick wipe-down for daily care or machine-wash the removable liner. Customize your look with the CCS Color System. Serious riders choose serious protection.
