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. 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.

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, the lightest and most ventilated extended coverage helmet available. We've teamed up with MIPS researchers to introduce MIPS SL—a new, ultra-light, and supremely comfortable version of MIPS that's available exclusively on Specialized helmets. With MIPS SL, we've essentially integrated MIPS technology within the helmet padding itself. MIPS SL's minimalist "watchband" attachment system provides 10 to 15 millimeters of rotation in every direction and offers the same brain protection benefits as other versions of MIPS, while also ushering in a new level of comfort and weight savings. Starting with protection, the Ambush boasts a significant amount of extended coverage, Energy Optimized Multi-Density EPS foam that manages the energy from impacts effectively, and a Aramid-Reinforced Skeleton that provides extra structure for the foam. Even with the added protection, though, it fits comfortably with our low profile and fully integrated Mindset 360 fit system. With its five height positions, this system provides unmatched adjustment, while an integrated dial allows for on-the-fly tinkering. The Ambush 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. 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 well in front of the competition. Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older. - New MIPS SL is the lightest, most ventilated MIPS protection to date and is exclusively available on Specialized helmets. - Patented aramid-reinforced skeleton provides internal EPS support. - Patented Energy Optimized Multi-Density EPS construction helps to manage impact energy. - Mindset 360 fit system provides a secure, customizable fit with 360-degree tension adjustment, five height positions, and an 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 stowage. - 4th Dimension Cooling System with massive vents, internal Cross-Channels, and aligned exhaust ports increases airflow to keep you cool. - Low profile in-molded shell with smooth, snag-free exterior shape. - Extended coverage for added protection and durability. - This helmet is ANGi ready, with a fit system mount designed for easy integration with our ANGi crash sensor. - Our available aftermarket ANGi sensor gives you and your loved ones peace of mind like never before. When combined with our Specialized Ride app, the ANGi sensor will evaluate the forces acting on the helmet in the event of an accident and, if necessary, send a text message to your specified contacts with your location. - Lightweight, quick-drying liner features a Gutter Action Brow that channels moisture away from eyes. - Tri-Fix web splitter for improved comfort and ease of strap adjustments.

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—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. 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.
