The Rab Women's Cirrus Flex Hoody is a lightweight synthetic insulator that feels lofty and packable like a down puffy. Since it's synthetic, the insulation stays warm in wetter, damper environments better than any puffy out there. The windproof, water-resistant outer offers reliable weather protection, and the stretchy fleece side panels provide better mobility than most insulators. The hood fits nice and snug under helmets, and like the jacket, it also has fleece panels for snug coverage. There are zippered hand pockets and an internal pocket for secure storage.
