Care Instructions:

Close all fastenings before washing. Use a gentle cycle at 30°C. Avoid bleach, chemicals, and fabric softeners. Tumble dry on low heat and iron at a low temperature if needed.

Our technical fabrics are designed to perform; fabric softeners interfere with their breathability and water-repellent properties, so skip them.

For insulated pieces, tumble dry separately on low heat with a few tennis balls to help restore the loft. No dryer? Give the garment a good shake and gently redistribute the filling by hand.
