Erima is a German company (that's been around for 115 years!!) They have affordable high quality workout clothes. In all kinds of colours, they are often used as kits for a specific team or club, but of course you can also just buy it for yourself.
Decathlon is French, so that's an option as well.
Ja daar zit zeker wat in. De tabletten zijn zinvoller bij iets langer aanhoudende crisis.
