Boys' Swimsuit (Rash Guard & Pants) 18-24M (86-92cm) *However, it fit my son perfectly when he was around 90-105cm. Purchased at a shop in a three-star hotel in San Diego, USA. (They sold items from the brand 'Snapper Rock Met Zealand' in a select shop style.) Made of polyester swimsuit material, the rash guard is quite sturdy. The rash guard has a zipper in the back to tighten around the neck. I used it for about a year, and it was well-maintained. Thank you.
