Product Information
Full details
The Rab Firewall Light Jacket is a high-performance waterproof shell designed for adult hill walkers and trekkers who prioritize mobility and protection. Engineered with 3-layer Proflex fabric, this jacket provides an excellent balance of 20,000mm waterproofing and 20,000g/m² breathability, ensuring comfort during intense treks. While it excels in wet, strenuous conditions, users should note that as a lightweight shell, it is optimized for packability and layering rather than heavy-duty thermal insulation.

FAQs
Is the Rab Firewall Light Jacket suitable for winter mountaineering?
It is designed primarily for trekking and hill walking. It works well as a shell for winter, but you must wear appropriate insulating layers underneath.
What does 20,000mm waterproofing mean?
This means the fabric can withstand the pressure of a 20,000mm column of water before moisture penetrates, indicating high-level waterproof protection.
Can I machine wash this jacket?
Yes, use a technical cleaner and follow the instructions on the inner care label to maintain the fabric's integrity.
Is the hood helmet-compatible?
The jacket is designed for trekking and hill walking; while adjustable, it is not specifically engineered for climbing helmet compatibility.
What is Proflex fabric?
Proflex is a proprietary Rab technology that combines the waterproof performance of a hardshell with the stretch and comfort of a softshell.
Troubleshooting
Water appears to be soaking into the outer fabric
The DWR (Durable Water Repellent) coating may have worn off. Wash the jacket and tumble dry on a low setting to reactivate, or apply a fresh DWR spray treatment.
Feeling damp inside during moderate activity
Ensure your base layers are synthetic or wool. Avoid cotton, as it retains moisture and reduces the overall breathability of the 3-layer system.

Setup, Compatibility & Care
To ensure the longevity of your Rab Firewall Light Jacket, pair it with moisture-wicking base layers to maximize the breathability of the 3-layer fabric. The jacket features a regular fit, which is designed to accommodate mid-layers like a fleece or lightweight down jacket comfortably.
Care Instructions:
- Wash in a front-loading washing machine using a technical cleaner designed for waterproof shells.
- Do not use fabric softeners or heavy detergents, as these can clog the breathability membranes.
- Tumble dry on low heat or follow the specific garment label to reactivate the Durable Water Repellent (DWR) finish.
- Always ensure the zippers are closed before washing to prevent damage.
