Clean aesthetic, comfortable fit, and a budget-friendly price—that’s what makes up the Align II. The standout feature of the Align II is the inclusion of the Multi-Directional Impact Protection System (MIPS), a patented technology designed to mitigate against rotational forces transmitted to the brain during certain angled impact scenarios. In addition, the Align II became the only $50 helmet to earn the highest Five Star rating from the independent testing done at the renowned Virginia Polytechnic Institute and State University. When including MIPS and earning this Five Star Virginia Tech® Helmet Rating™ we didn’t give up any comfort—the Align II includes the Headset SX dial fit system for easy fit adjustment, our 4th Dimension Cooling System for incredible ventilation, and an easy one-size fit system. If you’re on the quest for a feature-rich helmet that leaves some jingle jangle in your pocket, the Align II is for you. For helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older. - Align II earned the highest 5-Star Virginia Tech® Helmet Rating™ from internationally renowned Virginia Polytechnic Institute and State University. - The MIPS system is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts. - Easily-adjustable, one-size Headset SX fit system is designed for easy and accurate fit for a wide range of head sizes. Add in a micro-adjustable dial for on-the-fly adjustability and you're ensured an easy, secure, and accurate fit. - 4th Dimension Cooling System optimizes ventilation. - In-molded shell improves strength and reduces weight. -Reflective decals for increased visibility in low-light conditions.

The Switchblade MIPS is an ASTM downhill certified full-face helmet with a removable chinbar so you can easily switch to rowdy when it's time to descend. Everything about the Switchblade is optimized for the descent. That's why in addition to mandatory standards, it's also certified to ASTM-1952 DH with and without the chinbar. The chinbar is easy to remove - just push the buttons under the chinbar, rotate up, and take off—and it's just as easy to reinstall. Another boast-worthy feature on the Switchblade MIPS is the Roc Loc Air DH fit system, which has a bumper around the dial to prevent accidental adjustments if your helmet contacts your backpack or neck brace—all while keeping you cool. When the chinbar comes off, Wind Tunnel cheek pad ventilation adds even more cooling power as you start to climb. Plus, the full-cut style gives this helmet an aggressive look and provides ASTM certified coverage even when the chinbar is removed. When your ride is all about descending, your helmet should be too, and the Switchblade MIPS is the only removable chinbar helmet that is truly built for the down.

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.
