Review on Gildan Children's Ultra Cotton Youth Long Sleeve T-Shirt, 2-Pack by Rick Rogers

Priced for 2 packs you can't go wrong. The sizes weren't clear so I bought several sizes for my two sons. My 8 year old (58lbs and 4ft 2.5in) runs small. So I would say the small size is a size 8. My 13 year old (101 lbs 5ft 2.5in) fits in the large size. Size XL was too big for him and size M too small. If I had to figure it out, I would say Medium is a youth size 10-12, Large 14-16 and XL 18.
