Nordesco AquaDisk Pair

I like the smiley face, more fun than the generic disks. Also kindof handy to have two holes so it doesn't matter which way you pick up the disk. Small thing, but nice. My kids love that the swim instructors use them instead of kickboards to help kids practice kicking while learning what it feels like for their body to be in the water while they kick.

These are great for my three year old to grip on to and swim across the pool (with an adult close by). It gives her the confidence to practice her scooper arms and continue her kicking.
