IMO I would stick with multiple towels before resorting to a glove. Bring a couple of towels in zip lock bags and bust them our mid-round when you need them. Also when your hand and disc is mostly dry try a birdie bag or climbing chalk. After drying off said disc and head, keep them covered by putting it under your shirt until its your turn to throw. Gloves become just another unpredictable variable in getting a consistent release and with extra "tackiness" on the receiver gloves the residue might transfer to your disc which could become an extra mess.
