An update. I finally got to fish with it yesterday. I almost forgot I was wearing the pack. The only thing I think is missing is a rod holder. It's a small thing, but it's nice to have both arms and hands free to change flies, adjust tippet, etc.
For more accurate information, I took some measurements. I wasn't able to get these from anywhere during my search.
The front section is 13"wide by 8" tall. The two pockets measure 11" wide by 7" tall, that's the rear, zippered pocket with the fly tray / work surface. The front, zippered pocket is 7"wide by 3 1/2" tall. It's large enough to stack 3 tippet spools on the elastic corded tippet holder and stack 3 others,not attached to the pack, off to the other side. There are a couple of triangular pockets with zippers on each side at the lower corners, but they seem pointless, due to being so small.
The rear pack is 10 1/2" wide by about 9" tall. There are 3 pockets. They are 10 1/2" wide by 8" tall by 4" deep, 9" wide by 8" tall and flat and 7"wide by 8" tall and flat. I can carry a rain jacket, a bottle of water and wool hat in the largest pocket. The others I haven't needed yet.
The shoulder straps are 12 1/2" wide. I was concerned they would want to slide off, as one review I read on another forum suggested. They did not. They will allow the pack, laid out flat on the floor to adjust from a total length of 31" to 35". That doesn't sound like a lot, but remember it fit me, a vertically challenged individual. Others of the unfortunately tall denomination have said they are comfortable with the pack.
If I can figure out how to get my photos from Shutterfly posted, I will.
