This is a really nice suit for kids. The ventilated suit will really help in the summer, the zippers have nice huge pulls, basically all the details of an adult suit, mini-sized. I picked up a size Medium for my 53" tall son. The fitment was really weird - M is supposedly for 52-56" tall kids. The legs of the suit seem to be just barely long enough, I could see them being too short if he was any taller. However, the arms are still super long. It looks like it was made for a gorilla, haha. Ok, maybe that's extreme, but overall it does fit him for the most part, we're a little concerned if it will last much past this one year, but he has some siblings that can make use of it later if not. My son is looking forward to helping out more in the apiary this year!
