If you're looking for something discreet, I'd recommend checking out Vanquest or Mystery Ranch bags. I’ve used them before, and they have a nice balance of style and functionality without looking too tactical. They’re perfect for carrying a laptop, some gear, and even a handgun without drawing attention. I love how they have plenty of pockets for snacks and a water bottle too, so you’re not left rummaging around. Just make sure the size works for your MacBook Air, but they’ve been pretty comfortable for me overall!
