My experience with that…
Slashed the glove on a wreck and needed to re-seal my wrist seal. But, like a complete pollock, I’d tied string to my thumb loop. Prized the glove off with a bolt snap then spent way too long trying to stuff the string back into my sleeve, lifting the wrist seal and letting in yet more water in the process. Eventually manage it and had a very soggy arm.
Just imagine how you’d get a thumb loop off your thumb and back behind the wrist seal…
I now dive with a 10cm/4" piece of 2mm string which I stuff into the seal when I don the suit. Then it’s a simple case of pulling the glove off, pulling out the string then put the glove back on to complete the dive.
You don’t need fancy tubes, bungee, etc., just an off-cut of string. The air will sort itself out — as will the water when you cut the glove.
