BBB handlebar tape - 3.5mm thick (squishy!), and the texture seems effective (grippy!). The bottom end of the first side unraveled itself as I was trying to insert the plug after wrapping it (bad words uttered). I had to undo the whole thing to fix it. The second time, I put the plug in as soon as I could, and then finished wrapping. That worked a lot better.
