I have also been known to use packing tape to keep mitts on. I got Snowstopper mitts for my own kids this year, and included my dc parents in the order too since I had to order them online. So we will see what they are like once all the snow comes, but atleast I know that most of them will have mitts that can't come off or get snow inside the cuff (only one parent didn't buy the mitts, unfortunately she has the one thaf won't keep her mitts on - so I will definitely be taping them on).
