International Sweatpants Day - January 21st
(Last Updated On: May 4, 2022)


International Sweatpants Day on January 21st celebrates one of the comfiest pieces of clothing ever invented. It’s a day to don your sweatpants and wear them all day long! (Unless of course your school or place of work has a dress code).

In 1882 Émile Camuset founded the activewear company Le Coq Sportif in Entzheim, France. This company is credited with inventing sweatpants in the 1920s. The flexible and comfortable pants were designed primarily for athletes. Through the years, sweatpants have been called many things. Some of these include track pants, sweats, and jogging pants. Along with providing comfort, sweatpants were designed to keep athletes warm when they performed outdoors on chilly days. Despite the fact sweatpants were made for exercise, people wear them for the exact opposite reason – to relax!

Through the years, there has been an increase in sweatpants options. There are many colors and materials from which to choose. Some of the most popular sweatpants materials include cotton, nylon, polyester, polypropylene, and spandex. There are also various styles and types of sweatpants. Some of the most popular types of sweatpants include:

  • Baggy
  • Drawstring
  • Basic length
  • Cropped
  • Elastic cuff
  • Pocketed
  • Relaxed fit
  • Slim
  • Striped

How many pairs of sweatpants do you own? What are your favorite styles? Do you just wear them at home or when you’re out and about? If you love your sweatpants, you’re in good company. Celebrities like Kylie Jenner, Selena Gomez, Rihanna, Hailey Baldwin Bieber, and Carrie Underwood love their sweatpants so much they have turned this piece of clothing into a fashion statement. This is certainly much different than the days when wearing sweatpants outside the comfort of your own home was a serious fashion faux pas!
