Value Set: Gripscale Digital Luggage Scale + TLS Junior 25 Wheeled Duffel Sinful Red. When we set out to design the new Mother Lode wheeled duffels, we first turned to the experts â our Customers. Combing through thousands of testimonials, our goals were to identify the most (and least) loved parts of the bag, what were the key missing features, and what was the over arching mood of our customer. After 12+ months of development, we're confident the TLS collection will exceed your expectations. We kept the best parts of the orig. Mother Lode and added a number of new features: add-a-bag strap, expandability, compression straps, more zippered pockets, a flexible bottom compartment , an innovative patent-pending backbone for rigidity, and beautiful fabric. Enjoy! Bernard Majeau, Director, Product Development
