While not as big as your hands, I’ve had issues finding big enough padded gloves. Ended up using
Vibrastop gloves for the past 10 years now. Biggest I could find was XL, although Superior Glove lists bigger sizes now. I cut off the strap portion and they stretched enough to fit comfortably after a while. The padding is made for vibrating tools, which is what I originally ordered them for, and they work great for that too.
