Rab Cirrus Flex Insulated Hooded Jacket - Black

No, the jacket is not fully waterproof. It features a Pertex Quantum shell with a Fluorocarbon Free DWR (Durable Water Repellent) finish, which makes it windproof and highly water-resistant, suitable for repelling light rain and snow. For heavy or prolonged precipitation, a waterproof outer shell is recommended.

Yes, the Rab Cirrus Flex is designed for versatile, year-round use. It can function as a standalone outer layer in milder conditions or as a highly effective insulating mid-layer when temperatures drop, making it adaptable to various seasons and activity levels.

This jacket uses PrimaLoft Silver RISE insulation, which is a high-lofting synthetic insulation. It's engineered to provide excellent warmth-to-weight performance and, importantly, retains its insulating properties even when wet, unlike traditional down.

For best results, always refer to the specific care label inside your jacket. Generally, synthetic insulated jackets should be machine washed on a gentle cycle with a technical wash designed for insulated gear, at a low temperature. Avoid using fabric softeners or bleach. Tumble dry on low heat with dryer balls or air dry flat to help restore the insulation's loft.

The Rab Cirrus Flex features a 'Slim' fit. This means it's designed to sit closer to the body, optimizing thermal efficiency and reducing bulk for layering. It also features articulated sleeves for enhanced freedom of movement, particularly useful for activities like climbing.

While the Cirrus Flex provides excellent warmth, for extreme cold or static conditions during winter expeditions, it's typically best utilized as a highly effective mid-layer within a comprehensive layering system. For primary outer warmth in very harsh winter conditions, a heavier, dedicated expedition parka might be more appropriate.

The Cirrus Flex features a slim fit. Ensure you have the correct size. The fleece side panels are designed to provide stretch, but if layering heavily underneath, consider sizing up or adjusting your base layers. This jacket is optimized for active, less bulky layering.

While highly insulated, this jacket is designed for year-round versatility and dynamic use. For very cold or static conditions, ensure you are using an effective layering system underneath and consider adding a windproof/waterproof outer shell to trap more heat. Synthetic insulation performs best when paired with appropriate outer protection.

The Pertex Quantum shell offers water-resistance, not full waterproofing. It will repel light rain and snow, but sustained or heavy downpours will eventually penetrate. For guaranteed dry performance in wet weather, always layer with a fully waterproof hard shell over the Cirrus Flex.

Loss of loft can occur after extended wear or improper washing. Follow care instructions carefully (usually gentle machine wash with technical cleaner, air dry or low tumble dry with dryer balls). Regular, correct washing can help maintain the insulation's loft and performance.
