Product Information
Full details
The Rab Cirrus Flex is a lightweight, compressible synthetic jacket engineered for mountain enthusiasts who need thermal regulation during active pursuits like climbing, hiking, and mountaineering. By combining high-lofting PrimaLoft Silver RISE insulation with strategic fleece side panels, this jacket provides an excellent balance of warmth and breathability, though its hybrid construction makes it less windproof than a full-shell insulated jacket.

FAQs
Is the Rab Cirrus Flex waterproof?
No, it is moisture-resistant but not waterproof; it is designed to keep you warm even if it gets damp, but you will need a waterproof shell in heavy rain.
Can I wear this under a climbing harness?
Yes, the jacket is designed to be slim enough to fit under or over a harness, and the hand pockets are positioned to be usable.
How should I store this jacket long-term?
Store it in a cool, dry place hanging up or loosely folded, avoiding long-term compression in a stuff sack.
Is this jacket windproof?
It is wind-resistant, but the fleece side panels are permeable to allow for breathability, meaning cold wind may be felt through those specific areas.
What temperature range is this jacket for?
It serves as an excellent versatile mid-layer for active mountain use in cool-to-cold temperatures, but your base layer choice will dictate your overall cold-weather performance.
Troubleshooting
Insulation feels flat or loses heat
Tumble dry the jacket on low heat to help the PrimaLoft insulation re-loft.
Zip is sticking or difficult to pull
Check for loose fabric caught in the zip track and ensure the zip is free of grit or mud.
Fleece panels getting damp quickly
The side panels are intended for breathability, not water protection; wear a shell over the jacket in rainy or wet conditions.

Setup, Compatibility & Care
To maintain the integrity of the PrimaLoft insulation, avoid over-compressing the jacket during storage when not in the field. When washing, use a technical gear cleaner specifically designed for synthetic insulation and machine wash on a gentle, cool cycle. Avoid using fabric softeners, as these can compromise the moisture-wicking properties of the fleece and insulation. Always tumble dry on a low heat setting to help the insulation regain its loft. The jacket is designed to be fully compatible with climbing harnesses, with pockets placed to remain accessible even when wearing a harness or pack belt.
