Yeah... that's another good point. Gis are DAMN HOT and you sweat like a pig in them! And you think Karate Gis are bad? Try wearing a gi from a grappling art like Judo, Jujutsu, Aikido etc. - their tops are a lot thicker than a Karate gi (because they're constantly being grabbed and thrown about they need to be hardier)... those are really freak-ing uncomfortable!
