Setup: Simply put on the Thor III Fleece over your chosen base layer. Its full-zip design makes it easy to adjust ventilation as needed. Compatibility: This fleece is 'interactive' and specifically designed to be zipped into compatible Regatta Professional outer jackets. Look for the 'interactive' feature or zipper on your Regatta waterproofs or windproofs to create a complete 3-in-1 layering system. Care: To ensure the longevity and performance of your fleece, follow these guidelines: - Washing: Machine wash warm with similar colors. Always consult the garment's internal care label for precise temperature recommendations. - Bleaching: Do not bleach. - Drying: Tumble dry on a low setting or, preferably, air dry. The fast-drying polyester fabric allows for quick turnaround. Avoid high heat which can damage fleece fibers. - Ironing: Do not iron. - Dry Cleaning: Do not dry clean. Following these instructions will help maintain the fleece's anti-pill finish and wicking properties.
