K1X Swim Trunks I'm selling these because I bought a different pair. The size is M, but they run large. I'm 178cm tall, and they come down to about my knees. I wore an inner layer, so I never wore them directly. The waist has Velcro and a drawstring. The drawstring is attached to the Velcro, and it's a little frayed, but it doesn't affect the use at all. If you have any questions, please comment.
