Care Instructions: To maintain the performance features and durability of your Nike 7in Challenge Shorts, follow these care guidelines: 1. Washing: Machine wash cold with like colors. Avoid using bleach, as it can damage the `Dri-Fit` fabric and elasticity. 2. Detergent: Use a mild detergent. Do not use fabric softeners, as they can clog the fabric's pores and reduce its moisture-wicking effectiveness. 3. Drying: Tumble dry low or hang dry for best results. High heat can damage the polyester fibers and print. 4. Ironing: If necessary, iron on low heat, avoiding any printed areas or branding. 5. Storage: Store in a cool, dry place. Proper care ensures the longevity of the `Dri-Fit` technology and overall garment integrity.
