FAQs
Is this jacket machine washable?
Yes, it can be machine washed. Always check the internal garment tag for specific temperature settings and avoid fabric softeners.
Does this jacket have an internal pocket?
The Koster features two external hand pockets with secure YKK zippers.
Is the hood removable?
No, the hood is integrated into the design to ensure maximum waterproof coverage.
How breathable is the fabric?
It utilizes Helly Tech Protection, which is designed to be breathable, allowing moisture vapor to escape during moderate activity.
Is this suitable for winter hiking?
It is a light rain shell. While it is windproof, it lacks heavy insulation, so you may need to layer a fleece or mid-layer underneath for colder conditions.
What is the primary material used?
The jacket is constructed from high-quality, durable polyester.
Troubleshooting
Water soaking into the outer fabric instead of beading
The DWR coating has likely worn off. Wash the jacket and re-apply a technical water-repellent spray treatment.
Stiff or sticking zipper
Clean the zipper teeth with a soft brush to remove grit or debris, then apply a specialized zipper lubricant if necessary.

Setup, Compatibility & Care
Because the Koster comes fully constructed, no complex setup is required; simply adjust the hood and waist toggles to your preference upon wearing. To maintain the jacket's waterproof integrity, it is essential to wash it according to the manufacturer's care instructions, typically involving a gentle cycle with a mild detergent. Avoid using fabric softeners, as these can strip the DWR (Durable Water Repellent) coating from the polyester fabric. Periodically refreshing the outer shell with a water-repellent spray after long periods of heavy use will ensure the material continues to bead water effectively.
