Item is in good shape with plenty of life left and no known major issues with the zippers and buckles in working order. The wrap around your waist part is padded on the bag itself as well as the extra added part on the straps for comfort over time and distances. I am assuming this is at least water resistant due to the fabric but am unsure if it is waterproof. In the middle it is around 8.5" tall and 3" wide without it being stuffed full. The actual bag pocket inner part measures around 6.5" across but from one bottle holder across to the other one the full pack is around 12" across. Please refer to photos for condition and measurements or ask for more or any questions. If you are unfamiliar with the brand, refer to the measurements in the photos to compare to item(s) you own.
