I purchased this backpack for a motorcoach trip in September 2022, unfortunately purchased through Amazon and the time had passed to return it. I am disappointed with the item as it does not appear to be what I thought. I wasted money on this item very dissatisfied. First time and last time customer not at all what I expected.
