Review on Mancyfit Thermal Underwear Fleece X Small Boys' Clothing: Optimal Winter Comfort in Underwear by Rick Rownd

Bought for my 4 year old son as a base layer for his outdoor nursery. He's about 3 feet 4 inches and 36 pounds. The XS is obviously too big for him (which I expected when I bought it) but we just put our legs and arms together and everything is fine. He'll probably be perfect for him in a year or two since he's smaller. Seems to be of good quality and helps keep him warm for 5 hours in sub-zero temperatures.
