Lightweight, compressible and protective, the Men's ULTRA JACKET from On Running is essential equipment for trail outings in uncertain weather.
Its PFC-free waterproof 2.5-layer fabric incorporates GuardTecâ"¢ technology, which acts as a shield against rain while providing excellent breathability to evacuate perspiration during exertion™. Weighing just 124g, it folds into a mesh pocket on the hood for quick, compact storage in a bag or trail waistcoat.
Its slightly ample cut is designed to guarantee total freedom of movement and allow you to wear a small bag or a hydration waistcoat underneath, without hindrance.
