Product Information
Full details
The Rab Downpour Waterproof Jacket is designed for hikers and travelers who need a reliable, lightweight shell that remains easily packable without compromising on technical performance. It excels in wet conditions thanks to its high hydrostatic head and breathable 2.5-layer construction, making it an ideal choice for unpredictable mountain weather. However, users should note that as a lightweight shell, it is optimized for movement and ventilation rather than heavy-duty thermal insulation, meaning it requires appropriate layering underneath for colder climates.

FAQs
Is this jacket suitable for winter mountaineering?
It is designed as a versatile hiking and travel shell. While it provides excellent waterproof protection, it is thin and does not offer thermal insulation, so it should be used with warm base and mid-layers.
What does 20,000mm hydrostatic head mean?
It means the fabric can withstand the pressure of a 20,000mm column of water without letting moisture pass through, indicating a very high level of waterproofness.
Can I wash this in a standard washing machine?
Yes, use a gentle cycle with a specialized technical fabric cleaner. Do not use biological detergents or fabric softeners.
Does the hood fit over a helmet?
The hood is designed for general hiking and outdoor use; it is adjustable but may not be large enough to accommodate climbing helmets comfortably.
How breathable is this jacket?
It has a breathability rating of 20,000g/m²/24hrs, which is quite high and effective for active pursuits like hiking, especially when combined with the ventilation zips.
Troubleshooting
Water is soaking into the fabric surface instead of beading off.
The DWR coating has worn off. Wash with a tech-wash and tumble dry on low to reactivate, or apply a fresh DWR spray.
Feeling damp inside the jacket.
This is often condensation from sweat. Utilize the underarm zips to increase airflow and ensure you are not wearing too many layers.
Zipper is sticking.
Clean the zipper tracks of any grit or debris using a soft brush and water, then lubricate with a specialized zipper cleaner if necessary.

Setup, Compatibility & Care
To ensure the longevity of your Rab Downpour, keep the following in mind:
- Layering: The regular fit is designed to accommodate mid-layers. Test your preferred fleece or insulation under the jacket to ensure comfort before heading out.
- Cleaning: Wash the jacket periodically using a technical gear cleaner formulated for waterproof membranes. Avoid using standard detergents or fabric softeners, as these can strip the Durable Water Repellent (DWR) coating.
- DWR Reactivation: If water stops beading on the surface, tumble dry the jacket on a low heat setting to reactivate the factory DWR treatment. If that fails, apply a spray-on DWR replenishment product.
- Storage: Always ensure the jacket is completely dry before packing it away for extended periods to prevent mildew or membrane degradation.
