To be honest, I don’t know. I’m skinny as hell and it’s a bit loose on me, though every seat is. My friend bought another one exactly like this one (we split a pair someone was selling) and he fits in his perfectly, he said it’s nice and tight. He’s an average build so I’d say it’s a mid-small size, definitely not for a fat person.
I am a bit of a newbie when it comes to seat sizing, if you can tell me how to check/measure the size, I’ll be more than happy to get it for you.
Thanks.
