Boxer shorts (also known as loose boxers or as simply boxers) are a type of undergarment typically worn by men. The term has been used in English since 1944 for all-around-elastic shorts, so named after the shorts worn by boxers, for whom unhindered leg movement ("footwork") is very important. Boxers come in a variety of styles and design but are characterized by their loose fit. History In 1925, Jacob Golomb, founder of Everlast, designed elastic-waist trunks to replace the leather-belted trunks then worn by boxers. These trunks, now known as "boxer trunks", immediately became famous, but were later eclipsed by the popular Jockey-style briefs beginning in the late 1930s. The two styles, briefs and boxer shorts, had varying ratios of sales for the following fifty years, with strong regional and generational preferences. In 1985, in the U.S. men's briefs were more popular than boxer shorts, with four times as many briefs sold compared to boxers. Around that time many of the men who preferred boxers were older men who became accustomed to wearing them during their time in the U.S. military, and best selling color of boxers was white. Around that time boxers were beginning to become popular among young men, who wore boxers with varying colors and prints. Boxer shorts got a fashion boost in 1985 when English model and musician Nick Kamen stripped to white Sunspel boxers in a 1950s style "Launderette" in a Levi's commercial. Since the 1990s, some men also opt for boxer briefs as a compromise between the two. , one American manufacturer reported that woven boxer shorts made up 15-20 per cent of men's underwear sales, but had been declining in popularity compared to boxer briefs since 2003. Design Most boxer shorts have a fly in front. Boxer shorts manufacturers have a couple of methods of closing the fly: metal snaps or a button or two. However, many boxer shorts on the market do not need a fastening mechanism to close up the fly as the fabric is cut and the boxers are designed to sufficiently overlap and fully cover the opening. This is commonly known as an open fly design. Since boxer shorts’ fabric is rarely stretchy, a "balloon seat", a generous panel of loosely fitting fabric in the center rear of the shorts, is designed to accommodate the wearer's various movements, especially bending forward.
