Big Fan of these Swimsuits by SwimZip. Bought two styles, got lots of compliments & questions from other parents.

Pros:
1) Easy to get on/off (zipper). Way better than pulling a wet rash guard over your kids' head
2) Zipper flap keeps it from rubbing/scratching around the neck
3) Well made
4) Stylish
5) Quick drying
6) UV 50+

Cons:
None
