OK, got info from the embroiderer on the fitted hats.

They are closed (solid) back, meaning no strap or opening, and have a structured "dome" so they stay rounded on or off your head. They come in two sizes S/M and L/XL. They are flex fit so they stretch a bit to accomodate variations in overall melon size.
They'll be available in sandwich style (with a white stripe along the edge of the bill) and in solid style (no stripe). I'll have color info posted later tonight or tomorrow.
Cost for either sandwich or solid is $21.00 shipped. This includes a $1.50 surcharge by me, since this is now becoming more complicated and time consuming to handle. So on these hats there is a small bit of profit going on!

There is no price change for the original unstructured styles. Those who have already placed an order but want to change to a structured hat will be able to do so. I'll post instructions for that with the color samples later.
