Offering reliable, instant warmth and working hard to regulate temperature when output increases, the Xenair Alpine is an adaptable synthetic insulated hoody, perfect for alpine adventures on foot or skis. Built with a lightweight Pertex Quantum Air outer the jacket is highly breathable and weather resistant. It is insulated with two densities of recycled PrimaLoft Gold Active+ insulation, strategically body mapped to provide warmth where you need it and breathability in high heat areas. This effectively regulates temperature when the incline steepens or the temperature drops, maintaining warmth when static and increasing airflow on the move.
