It’s a very happy moment when we slip into our comfy clothes after a long day.
Who do we have to thank for that?
Wikipedia says the following:
The first pair of sweatpants was introduced in the 1920s by Émile Camuset. He was the founder of Le Coq Sportif. The sweatpants were simple knitted gray jersey pants that allowed athletes to stretch and run comfortably.
Thank you, Emile!
