After reading the reviews I decided to take a chance anyway. I chose 3x for my big/large hands. 3x fits me very well, not perfect but good enough. These mittens are not very high quality and look like they were sewn in a beginner's sewing lesson, but they are cheap. The fleece material is of acceptable quality and should keep you warm for a short time in mild to moderate winter chills. They are not waterproof and dry snow will stick to them. They are not designed for recreational outdoor winter sports.
