We ordered this for my daughter. She’s 5’10” and in very good shape. Based on the reviews and model sizing it was recommended to get the M/L size. However this was too big. I wanted to exchange this product for the Youth size and with paying for shipping both ways we didn’t exchange the product and ordered the youth size.
The youth size fits her but there is nothing that keeps the sleeve in place. We have a Bruce Bolt sleeve and it has a small rubber piece inside the sleeve that keeps it in place.
Overall the product is fine but there are better solutions as of now.
