I don't often write reviews if I'm honest, but I've felt compelled to for this bag. The bag in question, the one I bought from Amazon, is the K&F Concept KF13.025 V5 (Yeah, I don't know why K&F's product names are so damn tricky). After an absolute TON of research I settled on this bag and it arrived the next day. Now, after about a week of ownership, I can conclude that this is, indeed, the best camera backpack I've ever bought.I've gone through perhaps 4-5 Lowepro backpacks trying to find one that suited my needs, and none were exactly right. Not only that, but they were all a lot more expensive than this one! This one's ability to remove the waist strap is amazing, really amazing. I often use my backpack loaded with my camera gear, but I'm not that often on a long hike, therefore I don't really need the waist strap connected. Having a backpack with a fixed waist strap always gets in the way (putting the backpack in a car, straps get caught in the door, for example). Now with this bag, if I know I'm not going on a long walk or hike, then I won't bother connecting it. So good!The only negatives I can find is there is no dedicated storage pockets or places for memory cards. On all of my Lowepro bags over the years, they provide with little velcrow pouches which fit the size of an SD card, this bag does not have anything like that. Because of this, I've had to buy a separate case for my SD cards. Not so much of a bad thing really, as the case I've bought holds 8 memory cards & is waterproof. The only other "negative" this is the rain-cover is not physically attached to this bag. It comes in the front pocket with a cord on it which can be disconnected. It's good in the sense that it has the cord so its difficult to loose the rain-cover, however, I think I'd rather have a dedicated storage area for the rain-cover, and for the rain-cover to be always attached.Overall, so damn happy. Quality seems spot on, zip's are quick & easy, everything is great. The top handle is very sturdy, seems it would take a lot of weight & isn't uncomfortable to carry even with the bag fully loaded with gear. One thing I have also just noticed is the tripod holder on the side (I love it being on the side rather than in the middle at the back), is actually huge! I can carry my full-size tripod rather than my travel tripod if I wanted. Winner
