Care, longevity, and quick tips

To preserve warmth and fabric integrity, wash cold with like colors and hang dry when possible. If you choose a machine cycle, use a gentle setting and low heat. The fleece interior is designed to retain loft and comfort through multiple wears, so avoid high-heat dryers that can wear down fibers over time.
