Review: Exceeded my expectations. Highly satisfied. - My regret is not finding this brand earlier. I have experienced it all; shrinkage after first wash, falling apart straight out of package. My hope was thermals that would serve one season. I am pleasantly surprised by the quality, no shrinkage. My son says they are the warmest he has used thus far (5 star kid approved) I will stick with this brand moving forward;repeat customer. They run slightly big around the waist so hopefully he shall get two winters out
Review: Great for winter - Bought this and a white set for my son and it keeps him super warm! We live in the Midwest so we get really cold winters and my son loves how it keeps him warm to and from school, I have also had him wear it on outings to the city where it can get frigid cold and it keeps him really warm. Wears well under his regular clothes, not at all bulky. Would deff buy more as he grows out of them!

Very good thermal. My 10 year old loves to wear these thermals. They did a good job keeping him warm during our ski trip. They are very nice and soft and super comfortable that he continues to wear them at home on cold nights.
