OR has awesome products. You would have to try. Mitts are hands down (pun intended), warmer, better etc for warmth. Ever try putting on a pair of those little stretchy gloves when needing to do something and put your hand back in the mitt again?
Keeping your core warm helps your body pump blood to your extremities too.

If your core is cool, your body slows down to preserve your warmth for your vital organs. Long Distance Rider 101 Tech. Same thing off a bike.
i got the gloves. the, "cool, they work sitting on my couch test" has been passed. they would be really nice quality gore tex gloves without the heaters. a proper XL. no floppy fingers, and snug without straining joints, while permitting full movement. it is a winter glove tho. you'll need to remove the trigger guard on the AR for defending Finland, kylla.
