So, 2 full months after I bought my Shimoda Design Explore 40 backpack, they opened a Kickstarter for a new line of packs. Called the Action X series, they're basically a collection of improvements, many of which were universally requested by owners, including myself.
If you read my review, you'll know I really like my Lowepro Freeline 350 BP backpack. Despite all of it's improvements over the Peak Design backpack, there's one outstanding regression in the design and that's the shelving and dividers. Peak Design's origami inspired shelving system is possibly the best solution I've seen for carving up bag space to organize and protect your camera gear. Lowepro's solution is adequate but inferior. So I decided to combine the best of each into a FrankenBag.
About a month ago, LowePro began to ship their newly design Freeline 350 Backpack. The one thing about the Peak Design pack was the fully configurable interior using a unique shelf design instead of a series of hook and loop pads. LowePro borrowed this interior design, improving it by making the whole system removable, not only to give the backpack more versatility but to make configuring it far easier. This was the first thing I noticed.
