Business trips with both briefcase and carry-on are burdensome and physically demanding. To avoid this, this briefcase seamlessly and securely connects to the matching carry-on luggage via Interlink, a magnetic-mechanical latch. Its shape is uniquely deep and narrow so it blends with luggage when connected, and so is more maneuverable in congested spaces and airplane cabins. Up to 15’’ laptops fit in its durable hybrid construction, which provides hard shell protection with a soft shell’s flexibility. A water-repellant and dust-resistant nylon mesh wraps the exterior, while soft nylon lines the highly organized interior.
