B&H Photo Video has a great deal on the highly-reviewed Think Tank Photo StreetWalker Pro Backpack — it’s now only $119.75, discounted $80 from the regular price of $200.
This is a very popular and well-made backpack that can easily fit a DSLR with attached 70-200mm f/2.8 lens, four additional lenses, and a flash. It is very well featured with a rain cover, quick release strap, and tripod cup with tripod strap. This bag has been replaced by the Streetwalker Pro V2.0 ($199), but is tremendous value at the $119.75 price point.
Covered by a Think Tank Photo lifetime warranty.
