FAQs

Is this jacket completely waterproof?

Yes, the Koster features Helly Tech Performance and is fully seam-sealed to provide waterproof and breathable protection.

Can I wear this in the winter?

The Koster is a shell jacket without insulation. It is designed for spring and summer and would need significant layering underneath for colder conditions.

How should I wash my Helly Hansen jacket?

Use a technical detergent, avoid softeners, and wash on a gentle cycle. Tumble dry on low to help reactivate the water-repellent finish.

Does the hood detach?

The hood on the Koster Rain Jacket is fixed but is fully adjustable for a secure fit.

What does 'seam-sealed' mean?

It means the interior stitching is covered with a waterproof tape to prevent water from entering through the needle holes.

Is the fabric stretchy?

The fabric is designed for durability and weather protection, so it has limited stretch compared to softshell gear.

Troubleshooting

Water soaking through the outer fabric

The DWR finish may be worn off. Wash the jacket and re-apply a DWR spray treatment to restore water repellency.

Feeling damp inside the jacket

This is often caused by trapped body heat. Ensure you are layering appropriately for your activity level to allow the breathable fabric to function correctly.

Pros and Cons

Pros

  • Excellent waterproof performance in moderate rain
  • Breathable material prevents interior moisture buildup
  • Lightweight and packable for travel or commuting
  • Adjustable features offer a personalized, secure fit

Cons

  • Not insulated for cold winter temperatures
  • Lightweight fabric may not be suitable for extreme brush or rugged backcountry use
  • Requires proper maintenance to sustain the DWR (Durable Water Repellent) finish

Setup, Compatibility & Care

To ensure your jacket performs at its best, adjust the hood and hem toggles for a snug fit when you anticipate heavy rain. The Koster is designed to be worn over light mid-layers, such as a fleece or long-sleeve base layer. Regarding care, always wash the jacket in cool water with technical garment detergent to preserve the waterproof coating. Tumble dry on a low setting or air dry, and periodically refresh the DWR coating if you notice water no longer beads up on the surface. Avoid using fabric softeners, as these can strip away the breathable performance of the technical fabric.
