Excellent product! My husband has to walk a long way into the Shipyard where he works and climb ladders to get to his storage locker. He was having problems with his back from using a shoulder strap lunchbox so he wanted to try this backpack style. It has greatly helped his back because it evenly distributes the weight. He carries five or six water or sports drinks everyday and his lunch so it has plenty of room. It has several storage areas as well. We are buying a second one to have a spare! LOVES IT!
