I wanted to write a review because I am really impressed with this set! For reference, my son is about 52.5” tall and 82 lbs. I purchased two sets for my sons to wear under their jeans horseback riding and for playing in the snow. Unlike just about every other pair of long underwear we’ve owned, this set has washed well without much, if any, shrinkage and keeps them warm. They haven’t mentioned feeling cold horseback riding since we started using these while layering clothes. Typically they wear this under jeans and a sweatshirt followed by a coat and they have been riding in temps in the 20’s.The outfit is warm and very comfortable. It doesn’t have the rough feel typical long underwear has and the fabric has a good amount of stretch. I would recommend these and I would also get a backup set because they like them so much. Can’t beat the price too.I’ve been warm water washing and putting them in the dryer and the fabric hasn’t changed feel or faded. It’s holding shape well too.
