Why do guys love yoga pants so much?

Hey I was wondering why do guys like yoga pants so much? I was out yesterday early in the morning. I was sick and I had to go out so I just tied my hair back shoved on some yoga pants and left. I just walked as the shop was only a five minute walk. As I was walking through guys where just stairing at my ass and a couple even cat called me (witch I can't believe still happens in the 21st century tbh)
