I bought four different sets of mouth guards for my 10-year-old who's on the bigger side. I bought one from another brand that said ages 11 and up and that thing was so large I didn't even try to fit it in his mouth. These fit perfectly, he loves them, they cost a quarter of what the rest of them do and he's still using it hallway through the season.
