This is the Think Tank Streetwalker photo backpack. It is one of the newer models by Think Tank and is the smallest of the 3 within the "Streetwalker" line. It was purchased primarily for a 10 day trip from California to Osaka Japan. I was looking for a bag that had a slim and smaller profile than many of the photo backpacks out there. I anticipated being in crowded areas and did not want my bag to be too big and obtrusive. The first photo of the bag shows the outside of the bag with a water bottle in the side stretch pocket. Each side of the bag has a zipper pocket and a stretch pocket (where the water bottle is). If the bottle is in the stretch portion, the zipper portion is hard to access and you can't put anything too big in there or the bottle may not fit. As with all Think Tank products, their build quality is excellent. I would have appreciated more stretch in the upper outside and upper lower pockets. Same with the outside zippered pockets. All of these pockets get tight when you fill them with items. Although, the good news with it is that it keeps the slim profile of the bag. The bottom of the bag could use rubber feet as well. I did not take a tripod on this trip, but the bag comes with straps for a tripod which will run down the outside center. As with all Think Tank products, their build quality is excellent.

Overall I am pretty happy with the bag, though it comes with a price as the bag retails for $140.00.
What works
Excellent build quality. Nice and slim/small profile.
Room for improvement
Outside pockets should stretch a bit more. They are too thin for most items. Maps and brochures have a hard time fitting well and end up getting crammed in.
