Troubleshooting

Zipper feels stiff or stuck

Ensure the fabric is not caught in the track and verify the YKK slider is aligned. Applying a small amount of graphite or specialized zipper lubricant can help.

Pilling on fabric surface

Avoid washing with rough fabrics like denim and consider using a fabric shaver to remove surface fuzz safely.

Setup, Compatibility & Care

To ensure the longevity of your Koster Sweat Jacket, follow standard garment care practices. Machine wash in cold water with similar colors. Avoid using harsh bleaching agents or high-heat drying, as these can degrade the fabric quality and the elastic components of the ribbed collar and cuffs. For best results, air dry the jacket to keep the material soft and prevent shrinkage. Always verify your specific size against the manufacturer's size guide to ensure an ideal fit for layering.
