I hear you, but Product Type, Season, and Brand are all attributes whereby you filter a product. So you can create a page for Product Type by creating a template that pulls all of the possible values for a given attribute and generating a div for each. When you click through to one of the Product Types, you display a page of Product posts that is filtered by that Product Type. Then you can have, say, a sidebar that displays all the other attributes you can filter by (like Seasons). Something like the way Amazon presents its products. You have to visualize this as a relational database and imagine the data structures and their hierarchies.
