FAQs
Is this jacket truly waterproof?
Yes, it features Helly Tech Protection and is fully seam-sealed to keep you dry in rain.
Can I wash this jacket in a standard washing machine?
Yes, wash it on a gentle cycle with a mild detergent; avoid using fabric softeners.
What is the best way to restore water repellency?
After cleaning, use a dedicated DWR spray treatment to help water bead off the fabric surface.
Is the hood adjustable?
Yes, the hood is designed to be adjustable to provide a secure fit.
Is this suitable for heavy winter snow?
The Koster is a rain jacket; it is not insulated for extreme cold, though it can be layered over warm mid-layers.
Are the pockets waterproof?
The pockets use reliable YKK zippers to protect your items, but they are not considered submersible-proof.
Troubleshooting
Water begins to soak into the outer fabric
The DWR coating has likely worn off. Wash the garment and apply a spray-on DWR treatment to restore the water-repellent finish.
Zipper feels stiff or sticky
Ensure no fabric is caught in the teeth. If the zipper remains stiff, apply a small amount of dry lubricant or specialized zipper wax.
Feeling damp inside the jacket
Check that all ventilation points, such as the hood, are properly adjusted. If you are exerting yourself, ensure you are not wearing excessive layers beneath that trap sweat.

Setup, Compatibility & Care
To ensure your jacket maintains its protective properties, follow these care instructions:
- Cleaning: Machine wash on a gentle cycle using a mild technical detergent. Avoid bleach or heavy fabric softeners.
- Drying: Tumble dry on low heat or hang-dry to preserve the integrity of the water-resistant coating.
- Reactivation: If water stops beading on the surface of the fabric, use a DWR (Durable Water Repellent) spray treatment after washing to restore its performance.
- Storage: Store the jacket in a cool, dry place and avoid leaving it bundled up while damp to prevent mildew.
