Product Description
Light and packable, the Cirrus Flex is the ultimate year-round synthetic insulation. It’s versatile enough to accompany you on any mountain adventure, either as an outer in the warmer months or as an insulating layer when the temperatures drop. With its hallmark fleece side panels that breathe on the climb and reduce bulk, it’s easy to layer and offers superb freedom of movement.
