Product Information
Full details
The Rab Firewall Light Waterproof Jacket is a high-performance shell designed for hikers, mountaineers, and outdoor enthusiasts who need reliable weather protection without the bulk. Engineered with 3-layer Pertex Shield fabric, it offers an impressive 20,000mm hydrostatic head rating to keep you dry in heavy rain while maintaining high breathability during high-exertion activities. While it provides excellent protection for multi-day treks, users should note that as a lightweight shell, it is optimized for packability and movement rather than heavy-duty abrasion resistance against sharp rock faces.

Extended Product Information
FAQs
Is this jacket suitable for winter mountaineering?
While highly protective, it is designed as a lightweight shell. It works best for active use in varied weather but may require substantial insulation layers underneath in sub-zero temperatures.
Does the fabric have mechanical stretch?
The material is flexible and pliable, offering a good range of motion, though it is not technically classified as a high-stretch softshell.
How do I maintain the waterproof rating?
Keep the jacket clean. Dirt and body oils can clog the membrane's pores. Regular washing with technical cleaners will maintain the breathability and waterproof performance.
Can I use this for cycling?
Yes, its breathability and weather protection make it a great choice for bike commuting, provided you do not mind the hood flapping slightly in the wind.
What is the hydrostatic head rating?
The jacket is rated at 20,000mm, which is considered high and suitable for heavy, persistent rain.
Troubleshooting
Water begins to soak into the outer fabric rather than beading off.
The DWR (Durable Water Repellent) coating has likely worn off. Wash with a technical cleaner and re-apply a DWR spray or wash-in treatment.
Feeling damp inside the jacket despite no leaks.
This is often caused by trapped body sweat. Ensure you are venting by opening the jacket or adjusting your layers to match your exertion level.
Hood keeps blowing back in high winds.
Utilize the adjustment points on the hood to tighten the circumference around your head for a secure fit.

Setup, Compatibility & Care
To ensure the longevity of the Rab Firewall Light, follow these guidelines:
- Washing: Use a specialized technical garment cleaner (e.g., Nikwax Tech Wash) rather than standard laundry detergent, which can strip the DWR coating.
- Drying: Tumble dry on a low heat setting if recommended by the care label to help reactivate the durable water-repellent (DWR) finish.
- Storage: Store the jacket in a cool, dry place. Avoid leaving it compressed in a stuff sack for extended periods to prevent fabric degradation.
- Compatibility: The athletic cut is designed to layer effectively over light insulation or fleece mid-layers. Ensure your mid-layer is not excessively bulky to maintain the jacket's breathability and range of motion.
