This Sirocco Hoodie is engineered for non-stop breathability, designed to regulate temperature during a wide range of activities and conditions. It's the ultimate lightweight thermal regulator. Primaloft Gold Active+ insulation works alongside a FEATHERLITE Air fabric to trap warmth and resist wind, all while allowing moisture to move freely away from the body. Stretch materials, including THERMO Grid fleece side panels, work with the articulated fit to ensure complete freedom of movement. The result is a truly adaptable piece that can be worn as both a mid-layer or on its own.
