My boys LOVE them
Have 3 boys and they all love these! They are super soft and I have machine washed on gentle cycle with Woolite and then 'low heat' dried. I have also hand washed and air dried. Both worked great! I would recommend these for a great base layer the will help keep you warm and dry!! My 7 year old has taken to sleeping in them, and he used to refuse to wear anything to bed. That's how comfortable and temperature regulating they are!
