The Legend X moves to a polycarbonate shell — the outer is paper thin, which makes this one of the lightest helmets they've built (400 g in a medium, 440 g in a large), with a hard EPS liner underneath doing the real work of absorbing impact.

The back dial Fit System anchors on both sides of the helmet, adjustable one-handed as the day turns. A magnet chin buckle snaps shut with gloves on. The airflow system moves heat up and out through three vents, and the technical grid fleece comfort liner pulls out and washes when the season catches up with it.
