CTM Kids Elastic One Piece Mitten Keeper Clip
Another great feature is that now when you hang the coat at home - the mittens will dangle outside the coat allowing it to easily air dry when needed. You won't be stuck with damp mittens that had been stuffed in a pocket overnight. No more leaving mittens behind at day care or rushing around the house trying to find them on your way out the door. Adjustable for various fits up to 48 inches.
