Lowepro BP 450 AW III Reviews

Large, durable, comfortable

It's a great bag, it can fit everything, just take a lot of time to organize the compartments properly at first. I once dropped it, fully loaded with lenses and a camera, but nothing happened to the bag or the components inside.

More functional and better looking, but...

Recently went from the somehow odd-looking predecessor, the ProTactic BP 450 AW, to the BP 450 AW III. Interestingly, the slightly larger successor appears to offer a bit less space in my case, but is much more convenient regarding its laptop compartment (I usually have a large laptop with me), and the additional pockets on the outside are great as well. Overall, the bag is more functional, both on the inside and on the outside, and - don't judge me - I think it is also much better looking. Unfortunately, the folks at Lowepro also redesigned the straps, which means I am now struggling with wearing comfort for the first time. The heavier, the more pain. To a point where I consider not adding the laptop. I therefore don't think this relationship is going to last long. But at least I have a reason to shop at my favorite camera store again.

The Lowepro ProTactic BP 450 AW III Backpack does not have a specific location for an air tag but there are plenty of pockets to place a small item like a memory card or air tag.
