I own several skorts, leggins and shorts from CarraLee. I have a M ant that is true to size. I wear them alternating depending on the run and environment. These shorts are super comfortable as a second skin on. The pockets are a convenient and handy addition at least for me to fit keys in. I don't use phone while running though. The fabric is terrific, light, breathable easy to wash and dry. I love the pattern and the crazy colours!
