I actually am using this for my 5 year old while he is at school. I was worried they would be very infant size, but the fit my son just fine, although he does have a smaller neck so maybe that is why. The Velcro is easy to use it isn't too loose that it falls apart right away, as of now anyway. The quality of the material seems to be very good as well. Not too stiff and not overly soft either, literally just right!
