Not bad
My son loves these. We bought them for a trip that we are going to on Friday but he has insisted on wearing them to bed since we got them. We will be putting them to the true test on Saturday cause we are going to the ice castles and these were meant to keep him warm under his snow pants and jacket. They are super soft and I wish I had a pair cause they really feel so cozy. The crotch area did rip even tho he has wiggle room after the first use but we don’t have time to go through the whole return and blah blah blah. I will let you all know how they do with cold climates for anyone wanted them for that purpose :) Read more
Great thermal base layer.
Very nice quality. Fits true to size. Perfect as a base layer. Read more
Cozy for winters
So warm and cozy, my son loves it. Great to wear as a base layer in the winter. My son loved it so much I had to buy another. Yes, it does pill. But i think it's because the fabric is thin. Serves our purpose well. Read more
Seller should be banned!
This product deserves no stars and the seller should be banned by Amazon for selling used items. It arrived with the material all flaked with bubbles as if it had been used and washed numerous times. This is truly shameful. The material also very substandard. Read more
