This is a high poly model. I needed it for a spoof ad (see the label graphic which reads Volveau), and since it was the focus of the image, I needed the absolutely finest geometry for the result desired.
A useful addition is the cloth weave bump map. For cloth close-ups it looks pretty good.
The cap has a bump map for the ridges that is quite effective as well.
All the materials are designed for Cycles, but you can adapt them for BI with little effort.
