This fleece requires no complex setup; simply wear it. Its primary compatibility feature is its 'Interactive' design, meaning it can be zipped into any Regatta Professional jacket specifically designed to be 'Interactive' compatible. This creates an integrated, warmer garment for colder conditions. For care, it is recommended to machine wash cold on a gentle cycle. Do not bleach. Tumble dry on low heat or air dry to preserve fabric integrity and softness. Do not iron or dry clean. Proper care will help maintain the `anti-pill` properties and overall longevity of the fleece. Always check the garment's specific care label for the most accurate instructions.
