I have been looking at the 15L Peak Design Zip Backpack for quite some time but resisting because I felt it was to expensive for my wallet. I have been using two backpacks: the TOPO Designs, in their older version that was 20L in size, and the Lowepro Flipside Trek 350. I was using these two because I haven’t found one that met all my needs/wants. I am very much aware there is no perfect camera bag/backpack and just wrote about it here but this one sure looked promising. I’m not sure if this seemingly lifelong obsession is GAS (Gear Acquisition Syndrome) or indigestion. Anyway, I finally pushed the order button on Feb 5th. Here’s what I think after a few weeks with it.
