Setup: The Thor III Fleece is ready to wear straight out of the packaging. As an 'interactive' fleece, it's designed to zip into compatible Regatta Professional outer jackets. To utilize this feature, simply align the zippers of the fleece with the corresponding inner zippers of your compatible outer jacket and fasten them together. Compatibility: This fleece is designed as a versatile layering piece. It can be worn standalone in mild conditions or as a mid-layer under waterproof jackets, workwear shells, or heavier coats for added insulation. Its interactive design ensures seamless integration with specific Regatta Professional outer garments. Care: To maintain the anti-pill Symmetry fabric and quick-drying properties, follow these guidelines: 1. Washing: Machine wash cold (30°C) with similar colors. Avoid using fabric softeners, as they can reduce the fabric's wicking ability and breathability. 2. Drying: Tumble dry on low heat or hang dry. The quick-drying nature means it will air dry relatively fast. Avoid high heat, which can damage the fleece fibers. 3. Bleaching: Do not bleach. 4. Ironing: Do not iron. 5. Dry Cleaning: Do not dry clean. Proper care will extend the lifespan of the fleece and preserve its performance characteristics.
