We took two DLBPs and a Medium Yeoman to Disney world about 4 weeks ago. All of these were packed in our checked luggage and were for "on site" use. The DLBPs were to take to the park to carry sunscreen, a first aid kit, hats, sunglasses, water bottles etc. Generally we left each morning with the Burnt Orange DLBP packed inside the Nordic Halcyon DLBP. About half the time it stayed there and we didn't need need it. That was fine because the packs are so light they are not a burden and a folded up DLBP fits well inside the lower inner pouch leaving the upper pouch, the main inside body, and the front pouch free. We used the Yeoman to bring home souvenirs.
