Mountain Equipment Firefox (2012)

The Mountain Equipment Firefox is a well-established jacket that is made from Gore-Tex Active Shell, an extremely breathable and waterproof fabric. Unlike some other jackets the Firefox does not get extra reinforcement on the shoulders, but the benefit is a lighter weight (329g, men's size L). The jacket also features pit zips for extra venting when it is wet but warm, as even the best fabrics have their limits when it comes to condensation control. You also get two very large chest pockets that are mesh-lined for venting too. The hood is not quite up to the usual Mountain Equipment standards as it lacks a wired peak, but when on the head it fits and moves well, and the peak is still stiff enough to resist the wind and rain. The hood can also be neatly rolled down and secured at the collar to prevent it flapping about when running or biking. So functionally the Mountain Equipment Firefox is very good for fast and light action, but it does not fit quite as closely as other jackets and perhaps lacks some of the finesse of other designs that provide similar performance in a more stylish package.

Weight 329g (men’s L)

The Mountain Equipment Firefox is an ideal jacket for fast and light hillwalking and backpacking, but the baggier style means it is not so great for running or biking, even though the hood can be rolled down and secured.
