These trunks require no special setup; simply wear them as regular underwear. They are compatible with all types of outer clothing due to their slim, discreet design. For optimal care and longevity, machine wash the trunks with similar colors. Use a gentle cycle with cold or lukewarm water. Avoid harsh bleaches as they can damage the fabric and elastic. Tumble dry on low heat or, preferably, air dry to preserve the elasticity and cotton fibers. Ironing is generally not required for underwear, but if desired, use a low heat setting and avoid direct contact with the elastic waistband.
