This is a great looking, well constructed sling bag from Lowe Pro. I got it for a significantly discounted price with the 25% off 3 items and another stacking discount, so almost half off, which is why this even gets 4 stars. If I paid more I might dock another star.
Con - Usually I start with Pros for all of my reviews, but there is ONE MAJOR negative of this bag that makes no sense to me. The Velcro strips on the bag are fixed and sewn on to the bag's body, which limits how much you can adjust the dividers. When you are wearing the bag, the dividers are skewed so that the LARGER portion is on the LEFT side when you open the bag up to pull your camera out. Anyone with a DSLR knows, the RIGHT side is larger as that is the hand-grip area. What this means, is when you pull the camera out of the bag, you will need to turn it around before you can take pictures, instead of just pulling it out and ready to shoot with your hand grip in place.
Another Con is that the top portion of the bag does not extend down the entire length of the bag, some bags have this to allow for larger laptops or tablets, but you really get a camera cell, along with a slightly smaller compartment for random stuff.
Pros: overall the bag is extremely well constructed, looks good, well padded and streamlined. Still it is quite large, you would think it would hold more but it doesn't. You can definitely attach a monopod/tripod to the back or side, or put a small water bottle or thermos in the side pocket.
Overall good bag, just keep in mind the limitation, wish LowePro caught this in QA. Come to think of it, I will dock another star, this is a pretty egregious oversight imo.
