Hybrid – This unique construction features the best of both In-Mold and Hard-Shell constructions. The primary In-Mold construction makes the helmet incredibly light, while the secondary Hard-Shell upper allows for more advanced Active Matrix Venting™ and increased durability.

Active Matrix Venting™ – Active Matrix Venting allows you to regulate the airflow of the helmet vent system with the touch of your finger. Controlling large vents with minimal effort results in superior style and function that adjusts on the fly. It's climate control with the flip of a switch.

360 BOA® K2Dialed™ Fit System – All the benefits of the 360 K2Dialed™ Fit System, with the precision and quality engineered dial that you have come to know and expect from Boa® Technologies. Unparalleled comfort and ease of use.

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.

Level 3 Baseline Audio System – Pre-installed ear pads with a low-profile speaker that easily connects to your mobile device without hindering the fit or comfort. The on-cord controller is designed for on-the-go usability at your fingertips for talk or tunes.

Bluetooth Options (Sold Separately) – All K2 Helmets are now compatible with the Outdoor Tech® Bluetooth audio system, as well as other after-market audio options.
