These Nike trunks require no special setup; they are ready to wear right out of the packaging. They are designed for adult males and are compatible with all typical clothing styles, providing an essential base layer. To ensure longevity and maintain comfort, follow these care instructions: - Washing: Machine washable. For best results, wash with similar colors. Info needed: Specific wash temperature and cycle (e.g., cold wash, delicate cycle) to preserve fabric integrity and elasticity. - Drying: Air drying is recommended to help maintain the elasticity of the waistband and the fabric's shape. If using a dryer, select a low heat setting. Avoid high heat, which can damage the elastane fibers. - Bleach/Ironing: Do not bleach. Do not iron.
