Boardshorts
(重定向自Beach shorts)

Boardshorts, which were originally known as Surf Trunks, later as Jams, and occasionally in British English as swim shorts, are a style of men's and, more recently, women's summerwear. These shorts were originally developed for aquatic sports, specifically for surfing. In recent years boardshorts have become a popular form of general beach wear and all-purpose summer wear.
