Bests & Worsts Reviews from Amazon

Okay, so some reviews are not helpful as far as sizing. Here is my review and I hope it helps. I got a small, which fit my 4 year old that weighs 58 lbs and is 44" tall. He is in clothes 7/8 for t shirts and pants/shorts. He wears boxer briefs that are medium (8) in boys. These fit right one, true to size, if I went with medium it would have fit too and with the belt on it would be good, however it would have been longer but it has elastic at the bottom so it would be no big deal, as it can be tucked into the socks. The waist is at an 8, no bigger, no room for what a size 8 is in boys in most clothes. So he will use these once this season and then outgrow them which is fine. The material is thin, but I like it because it will be cool since it is black. This is for tee ball so no sliding and I do not know how they will hold up as far as sliding if I buy these again for baseball when he is older. I like the thicker waistband and the belt loops too. I bought two, and might return one and exchange it for a medium to try them out since I do have Prime. Take advantage of it Prime users, return things, you print a label if it does not meet expectations, Amazon is great with customer service. Anyways, I hope this helps.
