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. 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. New MIPS SL is the lightest, most ventilated MIPS protection to date and is exclusively available on Specialized helmets.
