I'm catching up with some mates at a pub to work on some game dev ideas and I'll be hauling my big-ass Legion laptop around in this bad boy: https://missionworkshop.com/products/shed-ap-messenger-bag

Amazing bag, completely waterproof, the asymetric straps are comfy af, bunch of pockets for cables and other gear. My standard loadout with it is laptop, Sony noise cancelling cans, kindle, and maybe weed and vape.
