Winter gloves/mittens

Hello!

Hopefully, this is a simple question. For years, my parents spent the winters in Florida, but now they are in a more northern state and still don't have all the warm clothes that they need. I would like to get Dad some gloves or mittens, but I had him try a pair of my husbands. Dad had no idea how to put them on, and, with his arthritic hands, I think that it is going to be a struggle for me, too. Any idea where I might go to get some "easy to put on" gloves or mittens for those times in the winter when we might need to get out?

Thanks.
