Think Tank Photo “My 2nd Brain”

Think Tank Photo recently introduced a new line of bags designed not for your camera, but for your computing needs, more specifically, your Mac-centric computing needs. They call it “My 2nd Brain” and it comes in four different sizes with three color options; black, harbor blue and green mist. The model I was sent is their largest, designed for the 15” Mac Book Pro, but they have other sizes which will accommodate an iPad and iPhone, the 13” Pro, the Mac Book Air and the 11” Mac Book Air.

The exterior appears very minimalist in design and function, almost as if its purpose was to hold just the laptop but when you begin to open up the YKK zippered compartments, you start to think, “what else can I put in here?”

The largest of the bags, the M2B15, which sounds like a character from Star Wars, is designed to hold your laptop, iPad and iPhone along with all the cords, accessories and power packs that Apple would ship with their products with additional room to spare.

The iPad compartment is located in front and is sized just for the iPad by itself but has soft materials so as not to scratch or harm your tablet. It will fit with one of Apple’s Smart Covers but nothing thicker. I regularly use a leather portfolio to carry my iPad around but was forced to remove it and replace with a smart cover to make it work. This was not a deal breaker for me. An alternative storage solution is to use the document sleeve in the back of the bag, which places it along the laptop so it is rigid and flat.  This section is wide enough to support a folio case.

The iPhone compartment, which can handle all generations of the iPhone is nice to have if you want to be completely be device free like in an airport security screening. Personally, I tend to keep my phone on me so in the future I might find a different use for this compartment.

Once loaded up and placed on my shoulder, my first thought was that I wished I had a Mac Air as my 15” Pro with disc drive suddenly felt heavier than I had anticipated on the shoulder. It wasn’t the fault of the bag design but with an iPad and all accessories in the bag in such a compact form, I was reminded of the behemoth laptops of yesteryear. I felt that if Think Tank came up with a backpack strap accessory like they did with the urban disguise camera bag, it would be perfect for commuting by foot or on a bike. To be clear, I experimented by attaching their shoulder harness v2.0 but it didn’t fit quite right with the d-ring placement on this bag.  It forced it to sit much lower on my back than it should. In its current form, it works perfectly for short distances like walking from the parking lot into an office or around a college campus.

The designated iPad compartment can only hold the ipad. It would be best placed closer to the laptop.


A backpack or sling strap accessory could improve long-term usefulness.

IN SUMMARY: Custom designed for the MAC fanatic who wants a catchall bag for all of their devices. A happy medium between Think Tank’s Shapeshifter Camera backpack and their Artificial Intelligence laptop sleeve.
