I bought two pairs for my 6yo daughter, one size small for her to use now and a size medium for her to grow into. Price was right and the half chaps are quality material so no fault there. However, they are not true to size. The chaps seem to be a bit on the smaller (slim) side so my daughter cannot wear the size small as the zipper will not even come close to closing but the length is perfect. The medium fits in the calf but is about an inch too long for her to wear now but she should be able to wear them at a later date hopefully.
