You can find an overview of this group test here: The best MTB helmet with ear protection – 6 jet helmets in comparison
Fox, FOX or Fox, the nimble and very clever mammal appears both in nature and on suspension components, protective gear and helmets in the MTB and motocross worlds. With the new Dropframe Pro, the Californian manufacturer sends its revised MTB helmet with ear protection into the race, complete with a fresh design and features that strongly resemble its full-face sibling, the Proframe RS.
Visually, the Dropframe Pro sits on a similar level to the Bluegrass Jetro in this group test. It looks substantial, robust and quite voluminous. The generous amount of material creates a larger crumple zone and therefore adds a margin of safety, although it also results in a somewhat bulkier appearance.
Both the construction and feature set are reflected in the weight though. At around 640 grams, the Fox Dropframe Pro is the heaviest helmet in the test field, followed by the Bluegrass Jetro, which is 58 grams lighter. In return, Fox pack in an extensive set of technical features. The adjustment system, developed in collaboration with BOA, uses fine cables instead of traditional plastic support arms and offers a wide, continuously adjustable range. The adjustment dial sits beneath the helmet shell and can easily be operated even while wearing gloves. The retention system can also be adjusted in height across four positions to fine-tune the fit.
To further improve comfort, Fox include an additional set of cheek pads that allow you to adapt the fit to your head shape. Another feature is the integrated MIPS system, designed to reduce rotational forces in the event of a crash. The helmet is secured using a magnetic FIDLOCK buckle. The triple-adjustable visor is clearly designed with goggle use in mind, and a GoPro mount can be positioned underneath it. The mount is included in the box, a nice touch.

When it comes to fit and comfort, the Fox Dropframe Pro sits in the middle of the test field. As far as sizing goes, the Dropframe runs slightly large, but for most testers it rested comfortably on the head. The BOA system then does the rest, ensuring a secure fit. You do need a little time to get used to the pressure the cables exert above the ears, especially when tightening the dial for a snug fit. In our test, however, this didn’t lead to pressure points. The padding can be removed and washed on a gentle cycle in a laundry bag. That’s a useful feature, because despite the 18 vents, the Dropframe Pro is one of the warmest helmets on test. On long climbs and in higher temperatures, heat build-up becomes noticeable, similar to the Troy Lee Designs Stage Stunt. The generous coverage comes at a cost here. On the other hand, it also creates a strong sense of protection. And the construction offers more than just a subjective feeling of safety. Hard facts back it up. Alongside the NTA 8776 certification for S-Pedelecs, the helmet also ranks 21st in the Virginia Tech helmet ratings, highlighting its protective performance across different impact scenarios. In the end, it comes down to priorities: maximum protection, comfort or maximum ventilation. If you are looking for the latter, the Alpina offers the airier alternative.
The Dropframe Pro also stands out in terms of noise, unfortunately not in a positive way. In other words, it’s one of the loudest helmets in the test. However, unlike the Bluegrass Jetro, where the noise mainly comes from wind, the Dropframe Pro produces creaking sounds from the material itself. These noises occur not only when putting the helmet on or taking it off, but also during aggressive riding in rough terrain.
Conclusions about the Fox Dropframe Pro
The Fox Dropframe Pro clearly focuses on maximum coverage, reinforcing the resulting sense of security with its certifications. The BOA adjustment system with its wide adjustment range, the extensive feature set including MIPS, FIDLOCK and a GoPro mount, as well as the adjustable fit thanks to the additional padding all highlight its high-tech ambitions. However, this concept also comes with noticeable drawbacks: high weight, significant heat build-up and a pronounced level of noise. If you are looking for a light and airy all-rounder, this is not the helmet for you. Riders who prioritise uncompromising protection, however, will find a helmet that’s consistently built around that goal.
