Specialized’s new radial tires might steal the spotlight today, but the brand is also releasing the newest edition of the long-standing Ambush trail helmet line, ready to protect your noggin. The short version: more ventilation (Specialized says it’s the brand’s best-breathing trail helmet ever), an adjustable visor, with provisions for mounting lights or cameras, and more “premium” touches such as a BOA dial and Fidlock buckle). And it still gets a 5-star safety rating from Virginia Tech.

I was a huge fan of the previous Ambush 2, and have put an unholy amount of miles and head sweat into it over the last two years, so I was excited to see an updated version hit the market, but also cautious, hoping Specialized hadn’t messed up my favorite trail helmet. Fortunately, this one is even better.

Specialized Ambush 3 Fit 

I have a fairly oval-shaped head that is 57 centimeters in circumference. I almost always wear size medium helmets, and the medium Ambush 3 fit me very well. It feels very similar to the Ambush 2, although it might offer a touch more protection to the back of my head. The new BOA FS1 fit system is a little easier to adjust than the dial on the Ambush 2, and I really like the flexible cord. It’s less likely to crack and break than the plastic straps found on some helmets, and it folds out of the way, instead of being stressed when you’ve got the helmet packed in your bag.

While the Ambush 3 fits very similarly to the Ambush 2, it does feel like it’s contacting my head less. It feels very airy and light on my head, with a lot of empty space.

Specialized Ambush 3 Features

The biggest shift for the Ambush 3 was the move back to an adjustable visor. I didn’t really mind the fixed visor of the Ambush 2, but it drove some folks nuts, and they’ll appreciate the four-position visor on this third edition. It’s a small detail, but I quite appreciate that the visor has a dedicated flat zone for a sticky mount for an action cam or light. It’s hard to run a light mount on many trail helmets, and it’s nice that the Ambush 3 doesn’t require a special aftermarket bracket.

Under the visor there’s hidden sunglasses storage in the two outside vents. The rubber flaps inside the vents grip the arms of your sunglasses securely. It’s easy to stow and deploy your shades, and I haven’t had any issues with them coming loose. This is another small detail that the Ambush 3 gets exactly right.

Inside the helmet, the Mips Air Node system creates a slip plane to help deal with rotational impacts. Historically I’ve found that the Air Node system holds up better to my toxic head sweat, and has less issues with pads falling out than other Mips systems, and so far that’s held true with the Ambush 3.

Finally, the buckle is a magnetic Fidlock number. It’s another tiny detail that I quite appreciate. Regular buckles are totally fine, but Fidlock is marginally easier to use, and on a premium helmet I’m always a fan.

Specialized Ambush 3 Performance

Specialized’s big story on the Ambush 3 is ventilation. The brand says it’s the most ventilated trail helmet it’s produced, with an AirCage internal rollcage, and 4D cooling system that sucks air in through the front and pushes it over your scalp. And yeah, I’d have to agree, the Ambush 3 is significantly better ventilated than the Ambush 2, and is one of the better ventilated trail helmets I’ve ever ridden in. I had a couple of nippy spring rides where it was honestly too ventilated, but now that things have warmed up a little I quite appreciate how well it moves air around.

The Ambush 2 did an exceptional job of keeping sweat out of my eyes, and routing it further back, down the sides of my face, and the Ambush 3 continues that trend. That, combined with the venting, means that I’ll be reaching for it all summer long. It also doesn’t help that it earned the same 5-star safety rating from Virginia Tech.

The old Ambush 2 was a pretty dialed helmet that fit my head very well. And it’s still available, at compelling discount prices. But, the new Ambush 3 refines all the details. The sunglasses holder is a little better, the visor is a little better, the fit system is a little better, the buckle is a little better, the ventilation is a little better. And all those “little betters” add up to create a helmet that’s significantly nicer than the previous version, and is currently my favorite trail helmet around.

For Now

Specialized’s Ambush 3 is a modern, full-featured trail helmet that’s very comfortable and well ventilated. That means it’s a great match for any ride that involves pedaling your bike up a hill and riding back down.
