The pack appeared to be what I wanted, but I did question the angle of the vertical zippers when I bought it. It appeared the zipper flaps would catch water running down it. I assumed Gregory had designed it to stay water resistant, so I bought it anyway. The first time I got rained on, I wound up with a 1/2 liter of water in the bottom. Items packed in zip lock bags were submerged and got wet. I wrote Gregory and told them of my experience (camera, which was in a plastic bag, got ruined) - they never responded. I will never buy another Gregory backpack.
