Very impressive bag which enables me to pack everything needed for a photo shoot. It fits a DSLR camera with attached 70-200 lens and still has space for another 2-3 lenses. The sling design enables fast access by swinging the bag from back to front. A top compartment fits a flash gun, filters, spare batteries, triggers with space to spare, and the side pocket is good for maps or documents. Also has an attachment with 2 straps to hold a tripod on the front.Access to the bag main camera compartment is through the side which is fully secure. The bag has thick padding throughout which protects the contents and also gives optimum comfort for when carrying with a heavyweight inside. The product description doesn’t mention it’s waterproof but I’ve tested in the rain and it was bone dry inside. Very impressive camera bag for the money.
