Whether used as a mid or outer layer, the advanced Primaloft® Silver Luxe synthetic insulation provides down-like warmth, lightweight packability and resilient loft in changeable mountain weather. Fast-drying and clump-free, it is evenly distributed throughout the micro-baffles for reliable insulation and an athletic, slim fit. Movement and breathability are a major strength, thanks to flexible, fast-wicking Thermic™ stretch fleece side panels. For extra convenience, the Cirrus Flex 2.0 Vest also features two internal stash pockets, a cord lock adjustable hem and an integrated stuff sack built into the left-hand pocket. From mountain hiking and winter walking to scrambling, climbing and via ferrata, this versatile, low-maintenance and sustainable piece will always merit a place on your kit list.
