100% had to leave a review how awesome this backpack worked for our family in Europe. Each member of our family was allowed to bring a carry on and a backpack for their luggage. But, we needed something for everyday use while we traveled to various sites, not a large carryon backpack. Enter this sweet little bag. It folded up nice and compact into our luggage and was extremely useful for day to day travel. It was very comfortable on my husband’s shoulders and could house a surprising amount of stuff! Sweatshirts, water bottles, snacks, first aid kit, you name it, we packed it in there. We went to several museums and tourist spots and none had a problem with the size of this bag. Also, one museum required (for security purposes) my husband to wear the backpack forward on the front side of his body, but he had no complaints that it was uncomfortable. The backpack held up incredibly well throughout our two weeks. It was perfect and can’t wait to use it again!
