HIGHLIGHTS
Featuring the trusted lightweight Mips rotational impact liner, in-molded upper and lower PC shells, and a redesigned three-position rear-height fit system, the new Roost combines trusted protection with cool comfort and looks.

ROUNDER HEAD FORM DESIGN
A new rounder head form gives the Roost a more universal fit, allowing more riders to find the perfect size.

TRUSTED MIPS PROTECTION
An industry standard for more than 15 years, the Mips rotational impact liner manages the forces of rotational motion, separating the shell and liner with a low-friction layer that slides relative to the head on angled impact.

EASY HEIGHT ADJUSTMENT
A dual-arm, snap-in, three-position rear height adjustment allows you to dial in the perfect fit.

TWO-LAYER PROTECTION
In-molded upper and lower PC shells provide optimal protective structure at a super lightweight.

OPTIMAL AIRFLOW
12 oversized vents keep you cool on the hottest days.

MIPS:
The Mips BPS (Brain Protection System) is designed to add protection in helmets against the rotational motion. The rotational motion is a combination of rotational energy (angular velocity) and rotational forces (from angular acceleration) that both affects the brain and increases the risk for minor and severe brain injuries. Mips BPS has been scientifically proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational energies and forces transferred to the brain.

VIRGINIA TECH 5 STAR RATING
In collaboration with the Insurance Institute for Highway Safety, Virginia Tech have rated a total of 128 bike helmets using the STAR evaluation system. The bicycle helmet impact tests evaluate a helmet's ability to reduce linear acceleration and rotational velocity of the head resulting from a range of impacts a cyclist might experience. Helmets with more stars provide a reduction in concussion risk for these impacts compared to helmets with less stars.
