The Firewall Jacket from Rab is a water- and windproof stretch jacket made of breathable, 3-layer Pertex Shield. It is ideal for year-round use in the mountains. It offers an innovative ventilation system with long YKK underarm zippers and the best protection even in damp environments. Thanks to the stretch fabric, it is extremely comfortable to wear, even with a lot of movement. Thanks to the helmet-compatible hood and the standard cut, additional layers can be worn comfortably underneath.
