My 9 year old son wears a medium size (8/10) of almost all brands. But this particular environment is huge. It actually says size 12 so be careful with the sizing. It's quite big on my son around the waist and I'm afraid if I wait a few years for it to possibly fit it might be too short at this point. The quality seems great, the fabric is comfortable but at the moment it doesn't even come close.
