Fit: This reverse dome oval crown, known to us as the "Wayne" crown, is great for egg and oblong head shapes. Depending on your head shape, the Wayne generally runs large for most. We recommend to size down if you are on the lower end of a measurement. While diameter is important, head shape plays an important role in fit and choosing the right crown style for your head shape.
