Description The Rab Men's Cirrus Flex Insulated Jacket is a lightweight, packable synthetic insulated jacket designed for year-round mountain use. Combining high-loft PrimaLoft® Silver RISE insulation with breathable Thermic™ stretch fleece side panels, it provides warmth where you need it while allowing excellent freedom of movement and ventilation during active pursuits. The 100% recycled PrimaLoft® Silver RISE insulation provides dependable warmth and resists clumping when wet, while the larger baffles allow the insulation to loft more effectively and trap heat. Thermic™ stretch fleece side panels reduce bulk and improve breathability, making the jacket particularly well suited to climbing, scrambling, hill walking, and mountaineering. A lightweight 20D Pertex® Quantum outer keeps weight and pack size to a minimum, with a fluorocarbon-free DWR finish providing protection from light moisture. The slim fit works well as part of a layering system, while the jacket can also be worn as an outer layer in milder conditions. One of the concealed hand pockets doubles as an integrated storage pocket for easy packing.
