I stopped buying tabs years ago and make my own single-layer Marshall style tabs from leather scraps. They are very easy to make, work well, cost next to nothing and you can have as many spares and customized versions (big or small holes, different shapes, etc.) as you want to suit your needs.
I usually wear a cheap brown Jersey glove under my tabs, even during summer. They cover hand glare well when hunting, are lightweight so don't cause any warm-weather problems, and are still warm enough for fall and most winter shooting. And, they are cheap/easily replaced when the need arises.
One other point. Leather tab fingerholes stretch over time...which is good for wearing over a glove but bad if the hole gets too big because the tab will tend to slide off the hand at the shot. I fixed that problem by attaching a loop of rubber (or leather lacing, but rubber works better) behind the finger hole. I simply put the tab on normally, put a twist or two in the loop, and lift it over my fingers and down/around my wrist. Adjust the tension by increasing / decreasing the # of twists. Takes about 5 seconds to do, the loop holds the tab (and the Jersey glove) nice and comfy snug, and no more loose/flying tabs.
