The backpack is great. It's not particularly cheap, of course, but it has several advantages over others. I actually wanted a backpack with a back opening that wasn't too big, as that's my daily travel companion. Unfortunately, I couldn't find anything suitable, so I ordered this backpack. I only take one camera and 1-3 lenses with me. I also wanted an additional compartment for small items and my wallet.

+ It's sturdy without being bulky. The material is very robust and stiff. It can even withstand being used as a pillow.
+ The straps at the top are flexible, making it very comfortable to wear.
+ It has a lot of padding and small pockets—you could almost say too many :-) The side pockets have additional zippers on the inside, so you can't reach them directly when opening them.
+ The top compartment can be expanded slightly upwards. It's perfectly large for storing small items like a wallet, tissues, keys, or even small snacks. The zippers can be secured with an additional buckle and are also sturdy. This prevents the compartment from opening easily and offers more security.
+ The same security applies to the front compartment. It is secured with two straps, which, however, can be easily released, but make it difficult to open "in passing."
+ The interior layout for cameras, etc., can be flexibly adjusted and is perfectly adequate for the amateur photographer.
+ The laptop compartment is double-padded. I don't really need it, but it's worth mentioning.
+ The bottle compartments on the side are also very sturdy; none of the bottles (0.75l) have fallen out yet (unlike my previous model, where that happened almost every time I put it down).

- Unfortunately, they open from the front and not from the back. That would be the final detail that would make the backpack perfect.
- I guess all the padding makes the backpack a bit heavier than others, but this is acceptable.

Despite the higher price, I highly recommend this backpack, especially if you're looking for something sturdy!
