I had specific requirements for a new backpack.
1: Carry 1 15.6" Dell 7567
2: Carry 1 13.3" Dell 2-in-1
3: Networking hand tools (snips, crimper, JackRapid, ect)
4: Specialty cables (console, USB-TTL, various HDMI and Ethernet)
7: Accessory Storage
Really the backpack does all 7, though I wish there were a hardened pocket for sunglasses but that's solved by just packing my glasses case.
The 13.3" 2-in-1 laptop fits perfectly well in the tablet pocket and the weight distribution is perfect, as the bag is comfortable to wear for extended periods of time. Like many I do field service and travel work and the 15.6" is my gaming/entertainment laptop and the 13.3" is where business gets done.
The only thing I'd change would be to add an external mesh pocket for a water bottle on one side vs a zipper pocket.
