The reason for my low ratings is due to the inaccurate size. They run very small, I originally ordered it for my grandson, however ; I gave it to my nephew whereas he's nine and my grandsons are 12.

Too small!
Size runs small. I would recommend them if the size was not such a big difference. If you order the actual size worn by the individual it was meant for it is useless, not just tight but TOO SMALL. Like them very much other than that. They are soft and warm feeling, but I am left wondering what size would fit, Two sizes up, three sizes bigger? No clue?
