Example Input: I love the "Ami&Li tots Super Lightweight Child Adjustable Ultrathin Sunhat for Baby Girl Boy Kids Toddler UPF 50". It is super lightweight. Since it is so lightweight I am grateful that it has a tightening chin strap so that it will stay on if it is windy outside. The material is very comfortable to wear. I am pleased with my purchase.

positive
