Certified protection, 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 revolutionary Multi-Directional Impact Protection System (MIPS), a patented protection against "rotational forces" caused by angled impacts. When including MIPS, we didn't give anything up to comfort though, the Align II includes our Tri-Fix web splitter, the Headset SX dial fit system for easy fit adjustment, our 4th Dimension Cooling System for incredible ventilation, and three universal shell sizes to achieve the perfect fit. 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. - 4th Dimension Cooling System optimizes ventilation. - In-molded shell improves strength and reduces weight. - Reflective decals help with increased visibility in low-light conditions. - 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. - With the Specialized Tri-Fix holding your straps in place and three shell sizes, riders can achieve an easy and accurate fit that accommodates 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.

When ripping down the trail, the last thing you need to worry about is if your helmet will protect you in a crash. Then again, you don't want to be stuck wearing a full-face on every trail ride. This is why we created the Ambush Comp with ANGi—a lightweight extended coverage helmet at a wallet-friendly price. Starting with protection, the Ambush Comp boasts a significant amount of extended coverage and a single density foam that's been reinforced by a Composite Matrix. The reason behind this is that it manages the energy from impacts more effectively. Even with the added protection, though, it fits comfortably with our low profile and fully integrated Mindset 360 fit system. And with its five height positions, this system provides unmatched adjustment, while an integrated dial allows for on-the-fly fine-tuning. The Ambush Comp also keeps you cool with our 4th Dimension Cooling System's massive vents and exhaust ports, so you don't have to worry about overheating—even on the hottest days. Our new ANGi Crash Sensor gives you and your loved ones peace of mind like never before—when combined with our iOS or Android app, the sensor will detect a crash and send a text message to specified contacts in your phone. It also syncs with our app and STRAVA to provide GPS-based activity tracking. Finally, we included a micro-indexing visor that quickly adjusts positions and has plenty of room for goggle storage. Combined, these features put the Ambush Comp well in front of the competition. - Composite Matrix internal reinforcement allows large vents for greater cooling. - In-molded shell improves strength and reduces weight. - Mindset 360 fit system provides a secure, comfortable fit with 360-degree tension adjustment, five height positions, and integrated dial for easy on-the-fly adjustments. - Micro indexing visor allows for a wide range of fast, secure on-trail adjustments, as well as convenient goggle storage. - 4th Dimension Cooling system optimizes ventilation. - Extended coverage for added protection and durability. - Tri-Fix web splitter for improved comfort and ease of strap adjustments. - MIPS-equipped. - Integrated ANGi crash sensor.
