I'm a beginner photographer and I have a few lenses and flashes and other smaller cameras - it all fits into this backpack! This backpack comes with customizable dividers that you can move around and fit to your personal needs and there are plenty of them included. There are also some elastic straps included to secure your lenses or other equipment. These are very much appreciated!The material feels great - probably water resistant - I haven't taken it outside in the rain yet. The bag also includes a small rain-guard which you can place over the bag. I think this is a GREAT feature. There is room for a small laptop or tablet behind the straps.The backpack is SUPER HOT to wear. I do appreciate the attempt to make breathable straps and a breathable back section; but no backpack will ever be perfectly cool. I hope the "water resistance" includes sweat resistance. I'd suggest not wearing it out on a super hot day if your'e worried about getting your straps all soaked in sweat. It does come with a handle on top of the backpack for carrying. Setting aside the warmth, its still a comfortable backpack to wear.All-in-all - buy with confidence - this backpack is worth the price as it comes with a lot of additional features.
