The Firefox is designed like an alpine climbing jacket with a slim cut through the chest, torso and arms but still roomy enough for a down mid layer underneath on cold days. It works fine as a ski touring jacket too.
The hood accommodates helmets and hats well with adjustments and a fit that doesn't obscure your view when you move your head. It is Mountain Equipment's lightest, breathable and most packable waterproof shell using Goretex Active. The Firefox is light enough to run in and has pit zips and mesh pockets you can open to enhance ventilation. At only 329g the Firefox is an excellent choice to take anywhere for a whole range of outdoor activities.
This top selling jacket from Mountain Equipment uses a tough 30D fabric across the shoulders and arms to make this the ideal jacket for those moving quickly through the mountains. GORE-TEX® Active fabric combined with an Alpine fit make the Firefox a remarkable lightweight performer.
