Okay, so my 4 year old is starting to take real hockey skating classes and needs to wear full gear. What is the smallest size jersey they make. I have a S/M on him right now and it is a dress. Even tucked in, it looks like a dress with large sleeves. Any help would be appreciated. PS...THE NEW HOCKEY GIANT STAFF SUCKS. Enough said with that. Hockey Tron and Hockey Monkey are 1,000,000 times better.
