I think Rick makes a fine tab. I actually need to order a large because although my fingers measure a medium when straight my ring finger bends crooked due to an old injury, sticks off to the side on the end and takes a rip from the string.
That said it's not easy to get away from the glove when it doesn't crease, smooth release, always in place on my fingers and holds up for thousands and thousands of shots.
As far as hot and sweat, this is Texas. You're not gonna escape that. My work boots and work gloves are soaked with sweat every day in the summer and they are leather. Set em out in that sun a bit and they dry.😆
Today you'd need a lined glove though. No sweat involved.
