I bought these breeches for my daughter and she loves them! She has an athletic body type, she is muscular and 91% percentile in height and weight for an 8 year old. We just sized up to a size large and she love them. The legs are a bit long, but these fit her body great. She says they’re super comfortable both in the saddle and around the barn. The fabric is soft and stretchy, and holds its shape. There have been no complaints about the waistband being tight or the pants being difficult to get on. They are stretchy and stay in place without digging in. These have become her go-to pair for lessons and trail rides. We’ll definitely be buying another pair for summer riding!
