I had to send the belt back 4 times because it was a 32 inch youth size. Do it right, Revain, like a real one. They have an ad with a 50 inch belt but continue to post youth sizes. Calling Mizuno got me $2 more than Revain, the right belt straight from the source. P/N 370147 is the correct part number for the 50" belt. 370148 is the youth size, which Revain continues to ship.
