This fleece requires no special setup; simply put it on. Its key compatibility feature is the `Interactive Zip Compatible` design, allowing it to be securely zipped into other compatible Regatta Professional interactive outer jackets. This creates a versatile 3-in-1 system for varying weather conditions. For care, this 100% polyester fleece is designed for easy maintenance. It should be machine washed on a gentle cycle with similar colors, using a mild detergent. Avoid using fabric softeners as they can reduce the fleece's wicking properties and cause fiber degradation. Tumble dry on low heat or, preferably, air dry to maintain its anti-pill finish and extend its lifespan. Do not iron or dry clean.
