Rab Cirrus Flex Insulated Hooded Jacket - Grey - XXL

PrimaLoft Silver RISE is a high-performance synthetic insulation known for its excellent warmth-to-weight ratio and ability to maintain insulating properties even when wet. It features larger baffles to maximize loft and heat retention.

The Cirrus Flex's synthetic insulation performs well even when damp and recovers quickly. However, for sustained or heavy rain, we recommend wearing a waterproof outer shell over the jacket to ensure maximum comfort and insulation protection.

This jacket is designed as a versatile, year-round insulator. For very cold weather, it functions best as a mid-layer within a comprehensive layering system, providing significant warmth under a protective outer shell.

The fleece side panels significantly enhance breathability, allowing moisture and excess heat to escape during high-exertion activities. They also reduce bulk, making the jacket easier to layer and providing superb freedom of movement.

Yes, it is designed to be very light and packable, allowing you to easily compress and store it in your backpack without taking up much space, making it ideal for travel and backcountry adventures.

It is an excellent choice for a variety of mountain adventures including hiking, climbing, scrambling, and general outdoor use, particularly in variable or damp conditions where its versatility and wet-weather performance shine.

Ensure the jacket is sized correctly to allow for full loft of the insulation, as over-compression reduces warmth. Consider your overall layering system; this jacket is designed as a versatile insulator, not a heavy expedition parka. For colder conditions, combine it with appropriate base and outer layers.

Verify you have the correct size; an overly tight jacket can restrict movement regardless of design. Ensure any underlying layers are not excessively bulky, which could negate the benefits of the fleece side panels designed to enhance mobility.

While the PrimaLoft Silver RISE insulation recovers quickly when wet and performs in damp conditions, it is not waterproof. For prolonged or heavy rainfall, always wear a dedicated waterproof outer shell over the Cirrus Flex to maintain optimal warmth and protect the insulation.
