Topside offers a new packing POV for when space is at a premium. Ideal for 3-5 day trips, this front-loading Carry-On opens from the top to let you pack deeper and includes a zipper expansion for an additional 2" (5 cm) of spaceperfect for those "one more thing" moments. We've added our first-ever back wheel brake system to keep your Carry-On from wandering off on trains or hills, plus a dedicated sleeve that keeps your 16" laptop within reach. It's the same hardside protection you trust, re-engineered for the tightest hotel rooms, train change-ups, and the boldest itineraries.
