Fox is a company that makes just about everything, for every action sport, that you can think of. However, their contribution to the mountain bike helmet arena has been solely in the form of hard-charging downhill helmets. The Fox Proframe changed all that. The Proframe is not only the helmet that brought Fox to local trails, but it has also been a driving factor in bringing full face helmets, in general, to the trails.

Weight & Ventilation

At 735 grams, the Fox Proframe is an ultralight full face mountain bike helmet by any standard, if slightly heavier than the TLD Stage. Furthermore, its 24 vents, which include huge cutouts in the chin bar make it the best-ventilated helmet in our test, just edging out the TLD Stage for this honor.

Safety & Safety Tech

The Fox Proframe features a molded, dual density eps foam liner for protection against both high and low G impacts. It also features the standard MIPS anti-rotational insert.

 

Meanwhile, padding is not the most robust in class, but it doesn’t feel skimpy either.

Frankly, there is not a great deal to say about the safety features of the Fox Proframe. They are not that complex, nor are they terribly innovative. But that is not necessarily a bad thing. The Proframe sticks with tried and true technology, and likely saves a few dollars and a few grams by doing so.

Visor & Additional Features

Like the Leatt DBX 4.0, the Fox Proframe uses a fixed visor. Like the fixed visor on the DBX 4.0, the Proframe’s visor does all of the things a visor should do, save for raising to allow goggle storage underneath on climbs.

 

Meanwhile, the Proframe features the popular magnetic Fidlock buckle, attached to well-padded straps that will not irritate your ears, like the straps on the TLD Stage.

One look at the Fox Proframe will tell you what a high priority ventilation was in the design of the helmet. In that vein, there is no mouthguard for the chin bar of the Fox Proframe. While this will not be a deal breaker for most, we would have like to have seen Fox include a removable mouthguard, like the one found on the Leatt DBX 4.0.

The Bottom Line

The Leatt DBX 4.0 is an amazing lightweight full face mountain bike helmet. It might not be as ultralight as the

There is just not as much to say about the Fox Proframe as there is about many of the helmets that we review. This is for two reasons. First, it does not utilize a ton of unique features that need to be explained. Instead, it relies on well known, tried and true technology to deliver a solid helmet. Second, it doesn’t include features that involve big tradeoffs with pros and cons that need explaining.

 

The Fox Proframe is a helmet designed to be lightweight, provide downhill certified protection, and unmatched ventilation. It does all three of those things and does them extremely well.


Finally, with a list price of $250, and sale prices as low as $175, the Fox Proframe is easily the best bang for your buck lightweight full face mountain bike helmet in our review, if you get a color that has been marked down.
