I purchased this small, inexpensive sling pack as an alternative to the much more expensive healthy back bags sold by other retailers. It's exactly what I was looking for at less than a third of the price. The backpack is significantly smaller and less bulky than an average backpack, but will hold a small laptop or iPad, a change of clothes for the gym, and other accessories in a compact space. It makes a good day pack for a hike or "personal item" to hold items during a flight and then stashed later in a larger carry on in an overhead bin.
