I found it listed here, but I would call the company first to make sure they have it in stock as everyone else shows it sold out. They may have simply failed to update their website inventory:

What I would probably do is set down with pattern books at JoAnn's and look for a front-closure smock to modify into an apron.
Edit: It may be that what you are looking for is a cobbler apron. Here is one for sale:

If you find an actual apron that you like, you could create your own pattern from it.
Amazon has some also:
