@skyfaller After our kids outgrew the kid's Flo masks, we tried a few - Zimi was the winner as it's easy enough for them to put on and they get a snug fit right away. And as a parent having to assist putting it on, it would be good too.
The foam inserts for the nose in the Zimi solve a lot of problems -
Trident was ok but harder to put on, as a kid and an assisting parent. It was harder to work out the nose without making it uncomfortably tight, or, not contoured enough.
