I just got back from a 1 month trip to New Zealand and Australia. I used this bag for all my electronics gadgets. It has a ton of space. There are so many separate compartments, I was able to store a SLR camera with a smaller telescope, laptop, iPad, several other small handheld cameras, adapters and voltage converters. I had around 30lbs total in this bag and we were on the go at least every few days. My bag has little signs of wear. I mainly wore it on the front to counter weight my travel backpack, which actually worked out perfect. The straps are adjustable enough where I was able to make it comfortable in any situation....front or back. The rain cover came in handy several times. There are three main compartments that you can get all the zippers close enough to use one lock on as well to deter theft. I stayed at a lot of hostels and luckily that was enough to not get my stuff stolen. Fully packed it fit in every overhead compartment in the planes we flew too (united, air pacific,tiger, qantas). The only airline I was worried about was qantas because they are super strict on weight limits and almost didn't let my bag as carry on. Luckily when they seen the equipment in there, they let me scoot by. All in all this bag has been amazing and protected all my equipment as it is pretty padded too. I may have looked like a little kid with an oversize backpack on the first day of school, but it exceeded all my expectations.
