Sportswear (or Active attire) is clothing, including footwear, worn for sport or exercise. Typical sport-specific garments include short pants, tracksuits, T-shirts, polo shirts and trainers. Specialised garments include wet suits and salopettes. It also includes some underwear, such as the jockstrap. Sportswear is also often worn as casual fashion clothing.

For most sports the athletes wear a combination of different items of clothing, sport shoes, pants and shirts. Some athletes wear personal armour such as helmets or American football body armour.
