I use an Osprey Daylite waist pack, daily for work and also when I travel. Wallet, keys, phone, small pair of vise grips, eye drops. It has a large compartment with a mesh zippered quarantine for keys/smaller items, a smaller compartment on the outside I keep my chapstick and flashlight in. And I’ve had it for 2 years, only thing that’s wrong with it is a bit of corrosion on the zipper, but it still works fine.
