I spent the last couple weeks experimenting with how gi jiujitsu grips transfers over to grappling normal clothing. The results may be shocking. Essentially if someone is wearing a hoody, most of gi jiujitsu knowledge would be imperative to understand if you wanted to have an advantage over your adversary. Check out these sparring rounds. And remember keenanonline.com does things differently and provides all manner of entertaining and educational grappling experiments as well as the most concise library of jiujitsu techniques that exists. Go sign up to fight your isolated boredom and learn some real skills that you can use in the streets (if you needed to). @hyperfly
