I'll warn you up front: this Kempton & Darrow brown leather laptop bag is pricey. Clocking in at $495, it's definitely an investment, but one that will stick around for years to come, thanks to its fine vintage leather and versatile number of uses. Get this — the bag was constructed to carry your laptop with the padded interior pocket, which keeps your machine separate from the rest of your daily essentials but is super popular among models, who can keep their portfolios flat from go-see to go-see. But we're not through yet. The Deceiver bag lives up to its name, thanks to a baby bottle holder, so you can also use it as a diaper bag. Talk about sticking with you for life.
