My daughter is 9...

I think the traditional orange ones are least comfortable, but actually work best to keep afloat.

The blue/yellow west marine ones are uncomfortable too. The vest is nice, but its the material.

I think the most comfortable is the neoprene vests. They havem at costco/sams club.

Keep in mind what goes on underneath also counts towards comfort. My daughter doesn't complain about the vest itslef as much as how hot it can get wearing it.

Best to let him try them and choose.
