I found a new source for UD logo clothing online. The company is called Johnnie-O and is mostly golf and some casual wear. They are a sponsor of the Dan Patrick show which is how I heard about them and then just randomly found the UD stuff on their site. The stuff is kind of expensive but there is a 30% off promo code(DAN) that is valid until June 19th. The links to the Dayton page and the promo code page are linked below.
