I am 6'1". I bought an XL. They are probably a little big, but the velcro is adjustable so I'll say they fit. If you skate vert or snowboard, buy some wrist guards. I have a friend that broke her wrist while snowboarding. It healed wrong and now she is screwed...for life.
Purchased size M in black for my 6 year old son. They fit. I hope they fit next year. Worth the price. He had cold hands, not any more. I have been using a pair of Dakine mittens on myself for over 5 years. They are durable, warm and waterproof.
They took a little while to warm up to. I tried them on and thought that they were too tight. I was thinking of returning them. I had them in a box for a week on the fence whether or not to return. I tried them on again and decided I really like them. You just have to accept the super skinny styling. Now they are my favorite.
