Specialized is back with the latest version of their popular trail helmet, the Ambush 3. The helmet addresses common rider complaints about all helmets, not just Specialized: heat buildup, poor ventilation, and integration issues with accessories.
In order to allow for larger vent openings without compromising safety standards, the helmet incorporates AirCage, which is an internal roll cage to support structural loads across the helmet. This isn’t the first time internal roll cages have been used in helmets for good reason – the internal supports allows designers to add massive vents without the EPS just exploding upon impact.
Taking advantage of that structure, the helmet features a 4D Cooling system that includes a widened mouth port for air intake, longitudinal vents with deep internal channels for airflow acceleration, and rear exhaust ports for heat release. The system works in conjunction with the AirCage to move air from front to back through the helmet. Compared to the previous Ambush 2, the Ambush 3 has more vents, specifically right across the forehead area. It also has an adjustable visor now (more on that below), and a cleaner profile.
Another big change is the addition of the BOA Fit System with FS1 technology (their name for the helmet dial), and Mips Air Node Pro impact protection. The combination is good for a Virginia Tech 5-Star safety rating. Just as importantly, BOA and Specialized seem to have cracked the code here for implementing the BOA system in a comfortable way. One of my complaints about existing BOA helmets has been that the cord was allowed to dig into your temple, which is made worse if you don’t have much hair. Here, the cord is captured in a guide that is tucked under the padding. The result is a snug but comfortable fit that doesn’t leave you with deep lines embedded in your temples after you ride.
As mentioned, the helmet now includes a 4-way adjustable breakaway visor. To allow for light and camera mounting, the visor itself has a flat spot on the top that is the perfect size for an adhesive GoPro mount or similar. However, if you want to run a light or camera on your visor, you’ll ned to use the Visor Lock tab, which pops into the visor adjustment slot and prevents it from moving. Realistically, this tab is so small, you’re going to have to try really hard not to lose it, but it does have a small hole that could be used to tie it to your camera/light bag. Our sample helmet has a bit of play in the visor adjustment system, which causes a bit of a rattle, but we’re hoping to get it swapped out to confirm it as an isolated issue.
Additionally, you’ll find hidden sunglass storage, adjustable (fore/aft) TriFix ear splitters, and a FIDLOCK magnetic buckle system.
The fit is quite good, and seems to match the claims from Specialized that the compact shell sits closer to your head.
