My child recently turned 14 and all of he pajama pants went right below his knees. I searched for a small mens pants that had a smaller waist line. Most american made pants are short and wide.  Bottoms
out was great with the adjustibal waist including a wide elasticband. This worked great and the length was perfect considering he will grow another 3 inches soon.  The flannel seems top quality too! I orderd 3 more pairs including a microfleece for camping.
