My u16 son wears Adidas Predator Pros which are about $150. He is very happy with the quality and fit. He gets 4-6 months of games and then demotes them to practice gloves for the next season. When he was young I was shocked that gloves didn’t last longer but now I’ve adjusted my expectations. I was actually just thinking his newest pair are really holding up. After 10 games they look almost new. When he was younger, we really liked the Reusch Orthotec line. Gloves are really a deeply personal thing. There are so many cuts and brand choices. I know a lot of people are fans of West Coast which are really reasonably priced.
Also, I’m not sure if your son is new to GK or not, but there are certain behaviors that shorten the life of a glove so if his gloves didn’t hold up, make sure he knows to get yo with his fist and not have the palm on the turf. Also, don’t grab the net.
