TLS Companion Duffel Blue Yonder. Details like a clean & simple organizer panel on the front (how many duffels have an organizer panel?), dual cargo pockets on the ends with super functional grab handles, a back pocket that converts into a pass-through for your trolley handle, and a really clever shoulder strap that totally disappears when you donât want it. It has to be tough, lightweight, and smart. Thatâs what qualifies the Companion Duffel as a member of the TLS family.
