Sweatpants are usually made from stretchy knitted jersey fabrics of differing weights, including single jersey, double jersey, fleeceback jersey, and loopback jersey (terry). They are a pull-on style pants and often have a flexible elasticated waistband with a drawstring closure. They may or may not have a fly and pockets. Some sweatpants can also feature elasticized cuffs at the hem of the leg. Sweatpants are traditionally ash gray in color but are now available in most colors. Traditionally quite “baggy” and loose, sweatpants are now also available in more form-fitting shapes; moreover, they have flexibility and comfort.
Once these practical pants were only worn for sporting events and at home. Now, they are available in many fashionable styles and are worn in a variety of public situations. Because of their comfort and fashion, they have become a popular choice of clothing. Sweatpants may come from many different materials and in many forms including thick and thin. Sweatpants are sometimes associated with certain lifestyles such as gym culture or hip-hop culture. This niche-specific perception of sweatpants since the 1980s has at times resulted in extensive dress code regulations with some outlets outright banning the wearing of sweatpants on their premises; including some german cafes and a substantial number of nightclubs worldwide.
