The HTW is a scunci model 17906-A, cut in half and rolled onto your penis like a condom. Its a very thin layer of cloth that does a good job of gripping, yet protecting my skin. I find I can put lotion on my unit (e.g. a small amount of cocoa butter lotion, or Eroset Vein Oil / EVO) and it still grips me just fine.

HTW: its a wrap
What What-A-Grip is a very thin rubber tube designed for a tennis racket handle. It does an excellent job of holding my HTW in place & I find its great for preventing slippage too— my #1 issue with the HTW is that it tends to roll up on its own. The What-A-Grip makes wrapping easier for me, and it doesn’t slip either—not with theraband (silver 22mil) on top of it.
I find the What-A-Grip by itself is not too comfortable, but I have found combining the two items doesn’t take much time at all, and I’m pretty comfortable hanging. Now I have been able to focus more on hanger settings & less on wrapping.

You can experiment & see what works for you. Avoid making your wrap too thick; that can cause issues, but at least for me, Theraband alone just didn’t work out.
HTW & the What-A-Grip are both pretty thin, so they don’t seem to be creating any problems for me. Sometimes if your wrap is too thick, you’re forced to make the hanger too tight (to prevent slippage), I’ve heard of guys bruising from this (e.g. an ace bandage + theraband—I’ve heard bad things about that).
