This is our first time with sunscreen clothing. Fit was as expected (M) for my almost 2-year old, and he does not mind wearing it at all.  We have used it every day for the playground and backyard for a few weeks now because I wanted to see if it really works before posting a review.  He is very fair and it really protects him from the sun.  I don't slather his face with sunscreen anymore (which he hated), and he has shown no signs of getting even remotely too much sun on his face or back of his neck. Some people may not like that the rim is a bit floppy, but it works well for us. I even bought a second one to keep at his grandma's.
