Lightest heat shrink sleeve?


New User
My local tennis shop tells me the heat shrink sleeve they use to perform a full grip size increase, from 4 1/2 to 4 5/8, weighs about .1oz (3g). Does there exist a sleeve this light? Everywhere I look I'm seeing more like .5oz. I asked them what kind they use and they can't tell me.


Heat shrink tubes exists for other than tennis handles. Perhaps they are using something designed to protect piping. The mass seems low, but not impossible, if the tubes are designed for interior usage.
