Helly Hansen Koster Rain Jacket - Yellow - S

The Koster Rain Jacket is designed primarily for rain protection and is lightweight. It does not offer significant insulation. For colder weather, it is best used as an outer shell layered over warmer clothing.

Follow the specific care instructions provided. Avoid fabric softeners and use appropriate cleaning agents. For long-term performance, consider applying a DWR (Durable Water Repellent) re-treatment spray specifically designed for waterproof outerwear when needed.

Helly Tech® Performance is Helly Hansen's proprietary technology that provides a waterproof and windproof outer membrane combined with a breathable lining. It ensures you stay dry from external precipitation while allowing internal moisture vapor to escape.

Yes, the hood is adjustable, allowing you to customize the fit for better protection against wind and rain.

The hand pockets feature zippers to keep your belongings secure. While the zippers offer protection, the pockets themselves are designed for convenience and may not be fully submersible.

The jacket is designed with a regular fit, suitable for layering. Some users find it runs slightly large to accommodate this layering capability.

Ensure all seams are properly sealed. Check the care label and ensure the garment has been washed correctly; fabric softener can impede water repellency. Consider a re-waterproofing treatment if the fabric's DWR coating has worn off.

Gently pull the zipper while ensuring the fabric is not caught. Apply a small amount of wax or lip balm to the zipper teeth to help it glide more smoothly. Ensure zippers are closed before washing.

Check that the inner lining is not clogged with dirt or detergent residue. Ensure the jacket is not being layered with excessively warm garments that could lead to overheating. Clean the jacket according to care instructions.
