The backpack has zipper compartments, straps to hold packed item in place, waist belt, lumbar supports, padded shoulder and back straps. Also contains a zip-off day backpack. I bought this and used it once for a Europe trip and it has been in my storage locker ever sicne. No rips, tears or any damage. Zippers all work well. The back pack measures 28" tall x 15" across x 10' deep. This is approximate as it does expand and these measurements do not include the zip off day pack. Can meet up in the KW area.
