This backpack is a beast, I bought it last year prior to making my way from British Columbia to Kingston. Only used it once on a hike in BC and I won't be using it in Ontario at all. For hardcore photographers with serious gear, this is the only bag you'll ever need. I used it to carry my Siga 600mm right in the middle of the bag. No scratches, or malfunctions of any kind. The price is fixed.
