My grandson had just outgrown his Hanes in size Medium, so purchasing the size Large seemed the logical next step, even though the size chart recommended buying the Medium.  When the Medium arrived, it was the same size as the currently outgrown underwear, so I exchanged the Medium for the Large, even though, again, the size chart specs seemed way off.  The size Large arrived and I assumed all was well and washed them.  Now my grandson is complaining that they are too large in the legs and are riding up.
