The Rab Downpour Trail Light Jacket is the ultimate companion for year-round mountain running, offering exceptional waterproof protection for extended adventures and back-to-back training sessions. Engineered with a cutting-edge 2.5-layer Pertex Shield construction, this hardwearing jacket keeps you running comfortably through even the most challenging downpours.
