Mountain Equipment Mens Firefox Jacket

Exceptionally breathable waterproof shell for fast moving mountain activity

{{ vm.state.webThumbOverlay.code }}

The Men's Firefox Jacket uses a tougher 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 Mountain Equipment's Alpine fit make this a remarkable lightweight performer.

Mountain Equipment have painstakingly developed their Alpine fit. It maps the fabric panels to the body, balancing weight and reducing unnecessary bulk while ensuring comfort and allowing a full range of movement. Innovative shaping between the waist and shoulders leaves the optimal room for layers underneath. A front seam with a reversed camber pulls the jacket inwards towards the body to reduce bulging as you lean over.

The Mountain Hood is engineered to provide weather protection while maintaining visibility and mobility. A twin-hoop adjustment system lets you control the hood volume for a precise fit. A triple-layered, laminated and wired visor keeps the elements away from your face, retaining its shape in the most difficult conditions. All adjusters are carefully positioned so that they are easy to find and operate, even when wearing gloves.
