This is my first time ordering from Zappos. The material seems comfortable. However, sizing is not accurate. They run a lot smaller. Size small does not fit a 2 year old. It was extremely difficult to put on. I couldn't put them on my son. Therefore, I couldn't tell the comfort level of these mittens. I also had to cut all the tags in order to tried them on the kid. I wasn't able to return them without tags.
