Rab Firewall Mountain Pants for men is a lightweight and durable shell trouser designed for demanding mountain tours and climbing in changeable weather. With waterproof and breathable 3-layer Pertex® Shield fabric, it provides reliable protection against rain, snow and wind, while being light enough to pack down and carry in a rucksack.

Full-length side zips make the trouser easy to put on over boots and crampons, and allow for quick ventilation when the intensity increases. The partially elasticated waist provides a secure and comfortable fit, while articulated knees and a long gusset in the crotch ensure good freedom of movement in steep and technical terrain.

Cord adjustment at the hem makes the trouser compatible with various types of footwear, and the waterproof YKK® AquaGuard® zips with storm flap provide extra protection against the elements. The trouser is made from 100% recycled polyamide with a fluorocarbon-free DWR treatment.
