The company you are thinking is Jarls of Lochlann which makes a product called the Kaber Kilt http://www.thejarlsoflochlann.com/Kilts/orsman.html . The Orsman has a removeable apron, so you can mix and match, but i con't think they actually sell a different apron than the kilt. No one hear has ever fessed up to owning one, though I have considered it based on the price.
