Product Information
Full details
The Helly Hansen Koster Rain Jacket is an ideal choice for outdoor enthusiasts and urban commuters who require reliable protection against unpredictable spring and summer weather. By combining Helly Tech Performance technology with a lightweight, fully seam-sealed design, this jacket delivers excellent waterproof and breathable performance. While it offers superior weather defense, users should note that as a lightweight shell, it is intended primarily for layering rather than providing heavy insulation in extreme sub-zero temperatures.

FAQs
Is this jacket windproof?
Yes, the Helly Tech Performance technology provides both waterproof and windproof protection to keep you comfortable in gusty conditions.
Can I put this in the dryer?
It is generally recommended to hang dry this jacket to protect the waterproof membrane and seam-sealing.
Is the hood detachable?
No, the hood is integrated into the design to ensure a continuous seal against rain, but it is adjustable for a better fit.
Does this jacket have an inner pocket?
The Koster Rain Jacket features external zippered hand pockets for convenient and secure access to your essentials.
Is this suitable for heavy winter use?
This is a lightweight shell intended for spring and summer; it is not insulated and would require significant layering to be used in winter.
How do I choose the right size?
The jacket follows standard sizing; check the product size guide and consider if you intend to wear heavy layers underneath when choosing your fit.
Troubleshooting
Water soaking through the outer fabric
The DWR treatment may have worn off; clean the jacket and apply a specialized technical DWR spray to restore water beading.
Moisture buildup inside the jacket
Ensure you are using moisture-wicking base layers; avoid cotton which traps sweat and prevents the jacket's breathability from working effectively.
Zipper sticking
Check for debris or fabric caught in the teeth; gently clean with a soft brush and avoid forcing the zipper.
Pros and Cons

- Lightweight construction perfect for travel and layering

Setup, Compatibility & Care
To maintain the integrity of the Helly Tech Performance membrane, avoid using harsh detergents or fabric softeners, which can clog the breathable pores. Wash the jacket in cold water on a gentle cycle and hang dry in a well-ventilated area. If you find the water-repellent coating starts to lose effectiveness over time, you can refresh it using a DWR (Durable Water Repellent) spray designed for technical outdoor gear. For optimal layering, wear a light fleece or synthetic mid-layer underneath during cooler days, as the jacket is designed to fit comfortably over base layers without adding unnecessary bulk.
