I just have the Photo Trekker and it is a big enough bag for my Toyo 45 with lenses and acces. so this one has to be plenty big and probably nicer than mine.
Mine is not AW though, wish it was. It is very nice to have the cover if it starts raining. I have to carry a trash bag just in case. Funny story though, I bought mine off of the auction site and the guy who sold it to me said it was used on Space Ship One project when he worked on it. Pretty cool.
