This first layer sweatshirt requires no special setup; simply put it on as your base layer. It is designed to be compatible with other athletic wear, fitting snugly under jerseys, training tops, or jackets without adding bulk. For optimal performance and longevity, proper care is essential. Always check the garment's care label, but typically, polyester Dri-FIT apparel should be machine washed cold with like colors. Avoid using fabric softeners as they can clog the fabric's pores and reduce its wicking ability. Do not bleach. Tumble dry on low heat or hang dry to preserve the fabric's integrity and elasticity.
