Boardshorts
Boardshorts usually do not have an elastic waist like many swim shorts do; instead they have a more rigid waistband which opens at the front, often with a Velcro (or similar hook and loop technology) fly. To be extra safe, the waistband is also held together at the front with a lace-up string (thin rope) tie. Because there are two ways they are kept from falling down, it is uncommon for boardshorts to come off and be lost in the ocean while surfing in rough waves.
