The Specialized Ambush is the California brand’s top-shelf trail helmet, and yesterday the third-generation Ambush was officially introduced. I’ve been testing the Ambush 3 for about a month now, and it’s quickly become my go-to helmet for daytime rides.

I just wish it didn’t cost $250.

Specialized Ambush 3 key specs

  • 21 vents
  • Three sizes and five colorways at launch
  • Fidlock chin strap buckle, four-position visor
  • Weight: 390g (size medium, tested)
  • Price: $250
  • Buy from Specialized

More airflow and a new mounting system

The Specialized Ambush 3 mountain bike helmet features a total of 21 vents: 5 along the brow (counting the two sunglasses storage holes), 10 on top, and 6 on the back. Actually, I’m not sure if the left and right top side vents count as one or three. Thin structural bridges effectively break the long vents into three pieces, but in practice do little to block air flow.

On unseasonably hot rides this spring, the Ambush 3 has proven to vent extremely well. And this sandy-gray colorway does a good job reflecting the sun, too.

The Ambush 3 introduces a new camera / light mounting system that integrates into the visor. This is a smart and safe solution, since the visor is designed to break away in a crash. A “visor lock” is included with the helmet to prevent the visor from moving around when you have the added weight of a camera or light attached to it.

Unfortunately, my test helmet didn’t ship with an action camera mount, and I couldn’t find a good way to mount my favorite lights without it. A Specialized representative tells me the camera mount will ship separately, though pricing and availability were unknown as of press time.

Fitting the Specialized Ambush 3

The Ambush 3 is offered in three sizes. I tested a size medium and found the helmet fits true to size. The BOA Fit System covers a wide range of adjustments and is easy to use. Unlike the BOA dials on most shoes, you don’t need to pop the dial to loosen it; just twist it counterclockwise.

The BOA dial on the Ambush 3 seems to prevent overtightening better than most helmets. Once the helmet is properly adjusted, it’s nearly impossible to add one more click. In fact, I thought I had maxxed out the adjustment on my helmet, but when I took it off, I realized I could tighten it a lot more. An overtight helmet can be incredibly uncomfortable, and this helmet makes it clear when it’s tight enough. Once properly tightened, the helmet is stable and rattle-free.

I’m a fan of the upgraded Fidlock buckle that can be fastened with just one hand. The chin straps are easily adjustable, soft, and don’t get tangled or twisted easily.

Adjustable visor and sunglasses storage

The previous generation Ambush 2 mountain bike helmet had a fixed visor, which was a major oversight. The Ambush 3 makes up for that with a four-position visor (most competing helmets have three-position visors).

There’s sunglasses storage too, and Specialized adds little rubber flaps for a bit of extra security. Personally, I don’t like storing eyewear on my helmet, but I know plenty of riders who really like this feature.

Safety first

The Specialized Ambush 3 mountain bike helmet is designed for everything from cross-country to trail riding. Featuring MIPS Air Node rotational impact protection tech, Specialized says the latest and greatest Ambush has earned a 5-star safety rating from the Virginia Tech helmet lab.

Interior pads are removable for washing, and if history is any guide, Specialized will offer replacement pads for purchase on their website.

Upgrades come at a cost

The Ambush 3 delivers significant improvements over the Ambush 2 — better ventilation, an adjustable visor, a magnetic chin strap buckle, and BOA fitment — but at a cost. The Ambush 3 weighs about 20g more than the previous-generation Ambush, and is significantly more expensive — $250 vs. $179.99. The pricing is in line with premium helmets from other brands — like the $270 Smith Forefront 3 — though it may be out of reach for many buyers.

Fortunately, it appears there are still plenty of Ambush 2 helmets left for purchase, and now they’re on sale for just $89.99.
