The body-mapped thermoregulating Polartec® Alpha® delivers insulation where you need it most and retains heat even when wet. The functional design reduces bulk while ensuring enough roominess for comfortable mobility when layered. Hydrophobic properties combined with lofted fibres on a mesh core ensure this jacket is quick-drying. DWR finish on the stretch nylon outer keeps light rain and spray out. A cinchable hood and sleeve thumbholes provide extra warmth.
