To use these boardshorts, simply put them on like regular shorts. They're great for swimming, surfing, or any water activities. When you're done, just hang them up to dry. Since they dry fast, they'll be ready for your next adventure soon. For maintenance, you can machine - wash them in cold water. Avoid using bleach as it might damage the fabric. Also, don't tumble - dry them on high heat. Just let them air - dry. And if the drawcord waistband gets loose, you can easily tighten it to fit your waist.
