Simplicity has always been our guide to the mountainsand our focus for designing headwear for high-alpine environments is no different. The Dome P is engineered to work with your helmet, so it fills a gap in your kit without complicating the rest of the system. It’s sleek yet notable, effective yet humble. It’s why our dome hats have been favored by alpinists and big-wall climbers for a quarter of century and counting.
