Lightweight and easily packable, the Cirrus Flex jacket is designed to be the go-to synthetic insulation for year-round use. It offers impressive versatility, serving as a reliable outer layer during milder conditions and as a warm, insulating midlayer when the cold sets in. Characterised by its signature breathable fleece side panels, it allows for excellent ventilation during ascents while keeping bulk to a minimum. These features make it easy to layer and provide outstanding freedom of movement. Updated with high-lofting PrimaLoft® Silver RISE insulation, the new design incorporates larger baffles that promote better lofting, enhancing heat retention. It delivers exceptional warmth-to-weight performance and maintains its insulating ability even when damp, making it a dependable companion for hikes, climbs, and scrambles in wet weather.
