I haven't tried the Macwet, just the FJ ones. Happy enough with them. I like to play with a glove on each hand if it's not warm (well above 10C), if it's not raining I quite often use a regular glove on my left hand (I'm R handed) and a rain glove on my right. I find them to be a little easier to pick small things like tees, ball markers out of my pocket than regular gloves.
I like the footjoy rain grip, they have always worked very well when wet. Like the fact that they now do a white/ grey version too as - dislike black gloves.
I find with the Macwets in the winter my hands get so cold when they are soaking wet and at their best but I lose all feeling in my hands, so now use cycling gloves from a well known online firm. They grip the club just as well and warmer hands. Only £15 ish too boot 😉😀
had the macwets, Mizuno and some FJ ones they were a bit of a muchness TBH, though the MW were double the price of the others.
one thing i did find with the MW was my hads were freezing as the were supposed to be kept wet, ther are suppose to be some that don't do this but never seen those on sale in any of the shops up here
Sealskinz are waterproof specialists. Not sure how they are for golf gloves though as the gloves have to aid gripping the club, not just keping your hands dry.
GP Multi Compound and MacWets, no better grip in the wet for me. I've found the MacWets don't need to be soaked through to get a great grip, sometimes I'll wear them all the way round on showery days.
I've been using Hrzl gloves for a while now. This has mostly been because they are longer lasting (though they do cost more I think they are better value for money in the end). They do work well when it's hot and sweaty. If it is really raining and they get wet I find that they will slip a little (and that's all that's needed for it to go wrong :-( ). They are made from Kangaroo leather and are a slightly thicker than normal gloves.
I have recently put in an order for some Falko gloves "FALKO ActiGrip™ technology is a unique leather embossing treatment that minimises the force required for a firm grip in dry and wet condition". We'll have to wait and see how they get on once we are out of lockdown. These are made from Buffalo leather (i'm expecting them to be equally thick).
