mont-bell Sahara Cap Kids 1108711 Size: Kids Free (51-54cm) Light Blue Worn several times, but there are no major scratches or stains, and I think it can still be worn. Thank you. Employs a material that combines UV protection and breathability. It blocks up to 90% of ultraviolet rays (test results with black fabric) and is also highly breathable. It protects the skin from the sun and is well-ventilated for a comfortable fit. * The UV protection rate is the measurement value of the fabric itself. Depending on the shape of the product, such as a mesh hat, the effect of blocking ultraviolet rays may be reduced.
