I use LeSport Sac Deluxe Everyday bag, as when they are empty they are JUST 12 ounces! Add all my stuff...and it's probably 4 lbs. I have to keep my bags light, as to not exacerbate my back! These are made of parachute material, and NEVER wear out. Once you are used to one, you have to get more. They are machine washable! The bottom of a purse, is now being said a big GERM haven! The compartments are so GOOD for an ADD mind, too! I only wish they had more fancy print black ones. They had one but it was gone in a second. We want some DRESSY black bags.............from Le Sport Sac. I would try one........especially if you want to keep it light.
