sizing
Size: 3X-Large, Color: Chocolate
Good quality, warm, sizing was dificult. I normally wear a size 12 shoe so I ordered an x-large but it was way too small. they shipped a size 11. Amazon was great with their free returns. I now ordered a xxx-large and they fit perfectly. x-large=11 and xxx-large=13
