FAQs

Is this sweatshirt suitable for hiking?

It serves well as a comfortable mid-layer for light hiking, though it is primarily designed for casual wear.

How do I ensure I get the right fit?

This model follows standard sizing. If you plan to layer thick sweaters underneath, consider the regular fit allows for standard layering room.

What is the weight of the sweatshirt?

The Koster Sweat Half-Zip weighs approximately 610g.

Can I tumble dry this product?

Air drying is recommended to maintain the fabric quality and longevity of the garment.

Does the ribbed collar lose shape?

The ribbed collar is designed for durability, but proper washing and drying techniques will help it retain its shape indefinitely.

Troubleshooting

Zipper feels stiff or difficult to pull

Ensure no fabric is caught in the track; occasionally applying a tiny amount of candle wax to the teeth can improve glide.

Fabric appears to have small pills after washing

Wash the garment inside out in a mesh laundry bag and avoid over-drying in a high-heat machine.

Setup, Compatibility & Care

There is no setup required for the Koster Sweat Half-Zip; simply ensure you select the appropriate size for your layering needs. This piece is highly compatible with technical base layers underneath or waterproof shells on top. To care for your garment, wash it in cold water on a gentle cycle to preserve the fabric softness and prevent pilling. Always zip the YKK zipper fully before washing to prevent snagging on other items. Air drying is highly recommended to extend the lifespan of the material and maintain the integrity of the ribbed edges.
