Medium size, nylon Healthy Back Bag. This bag is lightweight and perfect for travel. It has so. many. pockets. One side has a flapped Velcro pocket; the other has a zippered and a Velcro slip pocket. There is a deep pocket on the outside front for a small water bottle. Inside the bag is gray with black trim. There are multiple slip pockets, one zippered pocket, and a key clip. Hardware is an aged brass tone. The bag can worn over the shoulder or across the body, either front or back. Approximate dimensions are 17” high, 11” wide, and 5” deep. These bags are wonderful for travel when you’re out all day, and need to carry your essentials with you. Because they can be worn close, and in front, they’re helpful with security of your belongings in a crowded area. There are two minor spots on one side of the bag (last pic) that show more in the picture than they do in real life.
