I absolutely love this backpack! I bought the XS in Chai/Tan. Although it's small (13L), it holds a lot. I recently took it as a day pack on a trip to Europe. (It doubled as my seat bag on the airplane.) The inside compartment easily held my full size digital camera, iPhone XS, collapsing umbrella, Nook, sunglasses and 9 oz. water bottle. There is also an inner zippered pocket for small items like a nail file, clippers, etc. The zippered outer pocket along the backside of the pack is great for holding maps or a thin notebook or other flat objects. The two outer front pockets hold small objects such as a 2 oz. bottle of hand sanitizer, pocket tissues, lip balm/lipstick, pill containers, pack of gum, etc. The fabric is sturdy and the pack easily slings over a shoulder or can be worn on your back. (After three weeks of daily use the pack shows no sign of wear.) The drawstring closure under the flap w/magnetic snap closure ensures security. And the magnetic snaps on the front pockets keep them securely closed as well. I love this pack so much I recently bought a second one. Why? As the color of my first pack is Chai/Tan, it's on the light side. I found that I wasn't taking it if I was going somewhere where I thought it would get dirty (camping, baseball games). So I bought a second one in a darker color that won't show the dirt. Bottom line: great little day pack that holds all of the stuff I need without getting too heavy. What's not to like?
