I bought these for my 2 granddaughters ages 5 months and 2 1/2 years. Sunscreen is such a process and unpleasant experience for the 2 1/2 year old that this seemed like it might be a good idea, well it was a GREAT idea. Easy on and off, excellent sun protection, comfy and easy to play in the water or sun in, cool even on hot days. This is a keeper as they grow, we will keep sizing up. This product has made trips to the pool and park so much easier!!
