HIghs in the mid 90's heat index approaching 110, humidity so thick you can cut it with a knife. Two rain gloves is the way. I've been wearing the Finger Tens and swear by them. If I only wear one, my bottom hand just gets wet from the soaked glove on the top hand. I don't even bother taking them off to chip/putt, they are so thin it's not even an issue (and I can't stand chipping/putting wearing a single normal glove). The rub is they do NOT work if they aren't wet, they slide around on my hands (not the grip). White was out of stock so I ordered gray, but they sent black, so I just channel my inner Aaron Rai.
