Yeah, humidity doesn't get near as high here in coastal Southern California as it does in Florida. 50%-60% is normal here (we've had an extended period of 70-90% lately). I don't sweat all that much, and the amount I do seems to make for a nice cooling effect when used with a cotton T-shirt without making it a soppy mess. Cheers
