Warmth, packability, and versatility for year-round mountain adventures.

Rab says: 

Layer in winter or use as an outer in the warmer months, this versatile synthetic insulated jacket is perfect for year-round alpine use. With a fresh design that’s warmer than previous versions, it has an integrated storage pocket and updated fit.

Our Verdict

The Rab Cirrus Insulated Jacket combines warmth, durability, and packability for year-round use, whether as a winter mid-layer or an outer layer in milder conditions. Featuring recycled PrimaLoft Silver Rise insulation, it mimics down’s loft while maintaining warmth even in damp weather, making it reliable in unpredictable conditions. The recycled 30D Pertex Quantum shell, complete with a water-resistant DWR coating, effectively blocks wind and light rain.

With a weight of 482 grams (medium), the Cirrus packs down easily into its own pocket, which is ideal for stashing in a pack on longer treks. Practical details like spacious hand pockets, a chest pocket, and a fleece-lined chin guard add functionality and comfort, while elasticated cuffs and a drawcord hem help seal out cold air. This jacket is a great option for hikers and climbers who need a versatile, synthetic layer with a solid balance of warmth and durability for varying conditions.
