The sleeve covers only my glans, moulded into the end of the sleeve is a plastic loop; the sleeve comes with an elastic chord attached to the loop on one end, and on the other a leg strap for ADS. I just undid the knot from the leg strap and tied the chord to my cable clamp instead.
There is ZERO slippage with this setup using up to 8lb, I’m not saying it slips at heavier weights, that’s just as far as I’ve taken it.
As I said in a different post, I wouldn’t recommend using the same sleeve as me if your glans are under 4.5” in girth.
