Smaller and more structured than a classic messenger, more relaxed than a standard issue briefcase, the Core works with denim and a blazer and dress shoes if you must. The Core’s sleek exterior disguises its big functionality; a weather-tight flap and fuzzy liner keep your tablet and laptop safe and multiple internal organizer pockets keep you on point. A removable shoulder strap and luggage attachment strap lighten a heavy load but you may choose to go old school and carry the Core by its grab handle.
