A dense Turkish-cotton terry robe that actually dries a wet kid — the hooded upgrade pick.
If the robe's real job is drying a soaking child after the bath or pool, this Turkish terry is the one: absorbent, hard-wearing, and soft without being flimsy. It costs more than fleece and takes longer to dry itself, but it's the closest thing to a spa robe sized for kids, and it holds up wash after wash.
