A lightweight insulated jacket with Thermic stretch fleece panels and 100% recycled Primaloft Silver Luxe synthetic insulation. Ideal when temperatures drop but energy output is high and freedom of movement is essential.

Rab says:

When temperatures drop and you’re moving fast, the Cirrus Flex 2.0 Jacket comes into its own. It can be used as a soft, breathable midlayer for cold winter days or it can be thrown over a t-shirt for a lightweight warmth boost on chilly summer evenings at the crag. The PrimaLoft® Silver Luxe synthetic insulation retains its loft, dries fast and eliminates cold spots in changeable mountain conditions. Thermic™ stretch fleece panels at the sides promote rapid moisture dispersal, while helping the jacket move more freely with your body.

Built with recycled fabrics and insulation along with micro-baffle stitch-through construction for slim-fit breathability, the Cirrus Flex 2.0 Jacket features two internal stash pockets, an adjustable drawcord hem and articulated sleeves with semi-elasticated cuffs. Easy to layer, packable and effective in mixed weather, this is the practical, low-maintenance way to add flexible warmth to your outdoor layering system.

Rab's Cirrus Flex 2.0 Insulated Jacket has been redesigned with a change of materials. The jacket now features a lot of recycled materials including the Pertex Quantum outer, Atmos lining and Primaloft Silver Luxe insulation. These changes are a welcome addition and point towards more environmentally friendly trends across the industry.

The Cirrus Flex Jacket is a versatile piece of kit that uses synthetic insulation to provide reliable warmth no matter the conditions. Rab have changed the insulation used in the previous version to Primaloft Sliver Eco which provides a good balance of weight, performance and price. In in order to maintain the performance of the jacket they have kept the stretchy side fleece panels which allow for greater breathability and movement.

The usual hand warmer pockets with one doubling as a stuff sack, two internal drop pockets, adjustable hem and elasticated cuffs are the main features included. This versatile jacket will allow you to move effectively whether worn as an outer layer in mild conditions or as part of a layered system in cold conditions in the mountains without overheating thanks to the cleverly thought out design.
