Value Set: TLS Companion Duffel + TLS 29â Wheeled Duffel Solid Black. Tough Lightweight Smart â TLS truly defines the new Mother Lode series. We've completely re-designed our best selling wheeled duffels and added new features and innovative functionality and performance without added weight. If you're looking for outstanding design, style, and function, you'll find it in the new Mother Lode TLS series. 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.
