I got a pair of the FJ cart mitts with the slits as a tournament favor a few years back and use them religiously on cold mornings when I have to drive a cart. I simply roll the gloves back over my sleeves and play on. I tend not to take them off during the round, though as it warms up I often will remove them, especially the left one (I'm right handed so the left already has the golf glove). I've had great comments from my playing partners over the years I've had them, including during this morning's round. Weather started out about 40-45 and got up to the mid-to high-60s by the time we finished. Mitts stayed on through about five holes, then stayed in the cart until finished. If you can find them, go for it.
