[This review was collected as part of a promotion.] I bought two pairs for my daughter who is starting Kindergarten in the fall as her P. E. shorts and we couldn’t be happier. The XS will fit her the entire year and possibly into 1st since the waist is adjustable with the tie. They are lightweight, breathable, comfortable, dry quickly and the built in underwear is a nice plus, too! We will definitely be ordering more in the future.
