Purchased these for my son’s science camp field trip. Temps were at 30 degrees. They did keep him warm BUT the tops were too tight so he couldn’t use them at all. The pants are tight fitted(as I expected), but they won’t fit him for next winter unfortunately.He is about to be 12 yrs old & wears a 12-14 size in clothes.

My son loves these sets! I absolutely have to buy more… they’re the perfect size, very warm and very neutral colors which he also loves … Great price as well

I bought 2 grey pairs in XS (4-5) for my 2.5 year old and they fit very well so I bought two more pairs. The white shirt/pants and black pants fit, but the black shirt is SO tight I cannot get it over his head. I think it must have been mislabeled or just a malproduced piece. I already washed them so can’t return. Overall these are great, got some last year also that worked for a while - we like them for layering and even as pajamas. Will likely buy again, but hopefully will get the correct size pieces in the future.

I purchased a size 10 for my 57lb son because I’ve purchased other brands in size 8 and they were too small but this size 10 top fit perfectly but bottoms were too big they fell off. Good quality though

My 7yr. son love his thermals. They keep him warm. He wears size range 10-12 so I went with the large 12-14. The shirt fits him great. The pants a little long but he is ok with that. I'll be buying another pair.

These are so great! I read they ran small and they do. So I ordered one size up and they fit perfect after I washed them. My 2 yr old toddler had no complaints and they did the job and kept him warm in 20 degree weather. We used them under his clothes but I would use these as pj's if I nedded to. Also, you can't beat the price. These will be my go-to's when we take our ney trip to the snow.

It's strange that there is very limited choices as far as finding winter underwear for toddlers. I'm glad I found this brand. I did order a size up which turned out to fitting my little one quite well. I feel that the child will be more comfortable in the cold now that we have these. The two colors are very nice, there is a black set and a whitish set which is really nice. The price seems reasonable the quality is good. My child didn't complain about the texture so I'm sure the fabric is comfortable to wear too
