Button for listing product by type

[DBU]

My website has 3 images each representing a product type, namely T-shirts, Sweatshirts and Hoodies.

If a customer clicks on the "T-shirts" image, I would like it to display all the products labeled as "T-shirts"? Similarly,  for "Sweatshirts" and "Hoodies"

How can I get the url's for each of these and how can I acheive this?
