When it comes to cold-weather mountain missions, our clever Binntal Hybrid Ventrix™ Hooded Jacket is your secret weapon. It may look like your typical mountaineering jacket, but it’s made with Ventrix™ synthetic insulation that uses perforations on the back to prevent you from overheating as your body works harder. Its lightweight, highly air-permeable fabric coupled with moisture-wicking FlashDry™ technology means it’s breathable at the same time as being warm, regulating your temperature to keep you comfortable right to the end of the trail.
