Used Lowepro FastPack 350 Camera & Laptop Backpack.
A versatile bag with plenty of storage, the laptop compartment takes laptops up to 17″, the camera compartment will take a full frame DSLR and a few lenses, then there’s storage in the upper section for accessories/lunch, and a pocket on the side for drinks.
Generally in good condition throughout, it is used though, so you will see some darker areas etc just from that.
You can read Digital Photography Schools review of the bag, though I do agree the drink pocket is a bit shallow for bottles.
