Mammut Ultimate V SO Vest - The Ultimate V SO Vest Men impresses with its lighter and more modern design. It features a windproof, elastic, robust 3-layer GORE WINDSTOPPER material that can be used all year round and was developed exclusively with GORE, while wind and chin protection also fend off cold air. The jacket repels water thanks to the DWR treatment on the outer fabric. Membrane and light backing with an open 3D structure ensure optimal moisture transport and higher breathability. The wicking finish on the backing absorbs moisture from your skin and accelerates the drying process. Because the hem and collar ends are partially glued, they ensure a clean and technical look. In addition, they avoid friction on the skin, so nothing stands in the way of your adventure in the mountains.
