Full details
The Rab Downpour Waterproof Jacket is designed for adult hikers and outdoor enthusiasts who need reliable, lightweight weather protection that doesn't sacrifice packability. Engineered with 2.5-layer Pertex Shield fabric, it offers a robust 20,000mm hydrostatic head rating to keep you dry during heavy downpours, though its lightweight construction means it is best utilized as a versatile shell rather than a heavy-duty winter parka.

FAQs
Is this jacket suitable for winter conditions?
It provides excellent wind and rain protection, but it is not insulated. You should layer it over a down or synthetic jacket if you plan to use it in freezing temperatures.
How do I adjust the hood?
The jacket features a one-hand adjustment toggle, typically located at the rear or side of the hood, allowing you to cinch it down for a snug fit.
Can I machine wash the Rab Downpour?
Yes, it is machine washable. Use a mild technical detergent and ensure you follow the care label instructions, specifically avoiding harsh detergents or fabric softeners.
What does 20,000mm hydrostatic head mean?
It is a measure of waterproofness. A 20,000mm rating means the fabric can hold a column of water 20 meters high before any moisture penetrates the material.
Is the jacket breathable?
Yes, the Pertex Shield fabric is breathable, and the addition of underarm vents significantly enhances moisture vapor transfer during high-intensity movement.
What is the benefit of the storm flaps?
The internal and external storm flaps provide an extra barrier over the YKK zipper, preventing water from being pushed through the zipper teeth during sustained, heavy rain.
Troubleshooting
Water begins to soak into the outer fabric
The DWR finish has likely worn off; wash the garment and reapply a technical DWR spray, then tumble dry on low to reactivate.
Zipper is sticking or difficult to pull
Clean the zipper tracks with a soft brush and water to remove dirt or dried mud that may be impeding the teeth.
Condensation builds up inside during activity
Open the underarm vents to increase airflow and ensure you are not overdressed with too many insulating layers underneath.

Setup, Compatibility & Care
To ensure your jacket maintains its performance, keep the YKK zippers free of grit and debris. When layering, this jacket is cut to allow for a base layer or a mid-weight fleece underneath, but avoid forcing oversized bulkier items to prevent restricted movement. For care, wash the jacket in cool water with a specialized technical fabric detergent designed for waterproof gear. Periodically refresh the Durable Water Repellent (DWR) finish if you notice water no longer beads off the outer surface, and always air dry the jacket away from direct high-heat sources to protect the membrane.
