After much searching I have found some information on Xstream Fly Fishing and Outdoor Gear.
The website is out of date but, after talking with Sōs, I feel that they are out to make the highest quality and most useful vest out there.

Xstream web site
Prices:
Xstream Deluxe - $130.00 (This is one one described with a pocket in the rear to carry fish)
Xstream Regular - $85.00

The website lists an 1-888 number that did not work for me. I should be getting pictures of the vest(s) soon. Hopefully I will get them soon, as it is time to replace the old vest...
