The LGD was originally designed to be a waist pack AKA lumbar pack AKA hip pack AKA fanny pack. It also makes a great cross-body or one-shoulder bag: clip one of the optional shoulder straps to the d-rings on the side of the bag and you're ready to go. Tom Bihn retired LGD so this is a rare find. Measurement 13.5" x 8.5" x 2.5" I do not have the material for the LGD but below is the material information from Tom Bihn's website on the Le Petit Derriere * Exterior: bluesign® certified 630d High-Tenacity 2x2 Ballistic nylon * Interior: bluesign® and OEKO-TEX® certified 200d Halcyon/nylon ripstop * Zippers: #8 racquet-coil water-repellent zippers * Hardware: Duraflex®, Nexus, and Woojin buckles and related components
