I absolutely love this hat. It has a nice size brim and the crown isn't too tall for my tastes.
oorin is one of my favorite brands anyway, but to find them on Amazon was a nice surprise.
Be very careful to measure your melon exactly as they describe.  I would have ordered a large but the measurements came up medium each time.  I ordered the medium and it is a perfect fit.  I don't have the good boy, but my understanding is that this fits almost the same.
