This fleece jacket requires no elaborate setup; simply put it on and adjust the hem as needed. Its key feature for integration is its interactive design, meaning it's engineered to zip into compatible Regatta Professional outer jackets (e.g., waterproof shells). This allows you to combine the warmth of the fleece with the weather protection of a different outer layer. To care for your Thor III fleece, machine wash it cold with similar colors, preferably on a gentle cycle. Avoid using fabric softeners as they can reduce the fleece's breathability and anti-pill properties. Tumble dry on low heat or hang dry to preserve the integrity of the fleece and its anti-pill finish. Do not iron or dry clean.
