Hi, first post here so great to introduce myself. Im looking to up my business bag game. I work in a smart casual business environment, and like my ebags slim backpack very much. It is highly functional, has good but not top tier materials, and is extremely well designed. The problem with it is, Im adjusting to a new job and commuting routine that involves more trains and walking than in the past. Im pretty health conscious and pack 1-2 of my own meals today, and my current bag isnt big enough to accomadate this, at least not well. Since im going through the trouble of an upgrade, i want to get into something that looks high end, with that tier of materials. Im thinking leather, but am having trouble finding anything like that with the space or functions i want. Internet shopping involves some guesswork so im hoping for sone advice here. Im aiming for a bag, either professional backpack or breifcase/shouldee bag, with premium materials preferably leather, can be either classic design or good modern, that can hold laptops and work stuff, plus a good size tupperware for food, plus a feature to hold a travel mug, preferably built into thw outside, that will be durable enough to sling on my back on the train and that will be able to handle my home life with some exposure to rowdy kids. Suggestions? Thanks!
