The Mens Flux Pull-On from Rab works as a thin baselayer or light mid-layer to provide Supreme comfort during and post-activity, ideal for trips where a change of clothes is out of the question. The Thermic fleece construction strikes exactly the right balance between mountain warmth and fast-wicking breathability. Built from Thermicsingle jerseyknit with a brushed back and flat-lock seams for superior next-to-skin comfort. With high-stretch half-zip and low-profile thumb loops for ultimate in friction-free ‘ second-skin’comfort. It is also treated with Polygiene odour-control treatment, for reliable freshness day after day, however many high-energy bursts and intermittent rest periods the lifecycle of the garment involves.
