We love this relaxed denim style. This Toshi kids' sun hat includes:
 
A brilliantly wide brim for good sun and neck protection
UPF 50+ UV protection
A toggle tie on the head for adjustable sizing
A chin strap with adjustable toggle to secure the hat (and safety release clasp for peace of mind)
Outer is 99% cotton, 1% elastane. Lining is 100% cotton.
