Adaptable, lightweight, and versatile, the Xenair Vest is a dual weight, synthetic insulated gilet that excels in mixed conditions and start stop activities. Featuring a highly breathable, weather resistant Pertex Quantum Air outer and two weights of recycled PrimaLoft Gold Active insulation, it has been engineered to hold warmth when youre static and allow airflow as soon as output increases. Strategically body mapping the different densities of insulation, with the lighter weight insulation through the sides and down the spine, the gilet efficiently balances body temperature and eliminates the need to constantly change layers.
