I wanted a swimsuit that my son could wear all summer, offered sun protection and was very visible. At 4 months my son was already in 6-9m clothes so I knew I needed a suit that had a size range. This suit fits him well already while still leaving room to grow. I also love the color and the print, because I wanted an easily visible suit thanks to a swimsuit study I saw last year that showed that neon colors were more visible under water. We've only used the suit at indoor pools so far but im looking forward to the sun protection that the suit provides. The suit is easy to get on and off him, even when wet which is a huge plus!
