The Thule Subterra 2 Convertible Carry-On Bag adapts to our needs on every trip, going from backpack to duffel bag with a removable laptop attache that can be used as a briefcase. The 40-liter capacity is well-suited for short work trips or minimalist travel for up to a week, and the internal divider panel keeps our belongings organized. The super durable 800D nylon is water-resistant to protect our valuables from spilled drinks or rainy walks. Three external pockets ensure that we have quick access to our essential items, and we can tote our laptop with us either within the bag itself or in the removable attache with its own shoulder strap.
