Displaying products on my site using ultimate post type manager

So i’ve set up several categories. One being ‘hoodies’ for the hoodie clothing that we sell. The slug is ‘hoodies’. One post is called college so to access it you go to https://www.universityhoodiesdirect.com/wp/hoodies/college/. However, when you use the url https://www.universityhoodiesdirect.com/wp/hoodies/ a 404 is displayed. Is there anyway to create a category template for this, to list all posts?
