What is the Firewall Mountain Jacket?
It's a versatile waterproof shell jacket that's fully equipped for all manner of mountain adventures when the weather's not playing ball. Highly packable and protective, it uses Pertex® Shield technology for reliable waterproof protection.
What is it made from?
The Firewall Mountain Jacket uses a three-layer Pertex® Shield construction, which is a highly breathable, waterproof fabric designed for use in the mountains when protection, weight and breathability are key. This three-layer construction combines a waterproof, windproof and breathable membrane, robust 40D face fabric and a smooth lining made from recycled polyamide. The face fabric is finished with a PFC-Free DWR (durable water repellent) coating to encourage rain to bead off the jacket instead of soaking in, without the use of harmful forever chemicals.
Pertex® Shield delivers a hydrostatic head rating of 20,000mm and a breathability MVTR score of 20,000 g/m2/24hrs, meaning it offers great waterproof protection and breathability, making it suitable for various outdoor activities. The jacket feels soft and packable, making it an ideal jacket for stashing in your rucksack, just in case, without taking up heaps of space.
What are its features?
The jacket features a two-way adjustable hood with a flexible stiffened peak for essential protection from the elements which helps keep rain and snow away from the face. It can be adjusted with one hand, allowing you to tailor the protection or cinch it in close in harsh conditions quickly, reducing faff time.
A two-way YKK® AquaGuard® VISLON® front zip with a soft chin guard helps stop water ingress through the zip. It offers easy use with a climbing harness and can be unzipped from the top or bottom to provide flexible ventilation and mobility through the hips for steep ascents. Two YKK® pit zips offer excellent ventilation, allowing you to quickly dump excess heat when you're working hard.
For storage, there is a single YKK® AquaGuard® zipped chest pocket that's roomy enough for your essentials and allows quick access on the go. Fully articulated sleeves provide a natural range of movement for various outdoor activities, whilst the extended, shaped cuffs provide additional coverage across the wrists when reaching up or stretching. The cuffs feature hook and loop adjustments to allow you to achieve the perfect fit around chunky gloves or mitts.
Finally, a dual-sided rear hem adjustment, which can be adjusted with one hand, allows you to further seal out the elements, keeping warm air inside the jacket and cold drafts out.
