For technical all-year-round mountain athletes, the Cirrus Synthetic Nimbus jacket will keep you just as warm and cosy as down in changeable weather conditions.
The Nimbus is a technical all-round, micro baffled jacket packed with a superior quality synthetic filling called Cirrus. This new, featherless insulation has all the key benefits of down and has water-resistant fibres that expand and loft-like down feather to create a cloud of warmth around the wearer. It has the same warmth to weight ratio as a 600 fill power duck down equivalent. It lofts well, compresses into its own pocket for easy storage and resistant to moisture too. The Nimbus is the ideal choice for the climber who needs a light jacket with helmet compatibility, and the hiker who requires a warm mid-layer that can fit nicely under a waterproof shell when the weather turns nasty. This versatile jacket has three pockets for essentials and Lycra bound cuffs and hood to trap precious heat inside.
