Knocked the bark off my knuckles on the heavy bag the other day, so when it came time to do some grappling two days later, I knew I had to figure something out. So I went to Westbury Pharmacy and asked a home health specialist what he thought would be best. He said Elasikon. It was three bucks for the roll below.
So I put on bandaids and covered them with the tape before grappling. After a 90 minute session (30 of it grappling) this stuff didn’t budge. It’s also mildly water proof. When I wanted to get it off I had to soak it to get to loose.
If you want some rock solid tape, give it a try.
