Have used this pack almost daily for 4 years now. Can hold a change of clothes and shoes when needed. Perfect sized pack when you need to carry and have available or doff a layer, in addition to safety and day's use capabilities. The pack's "narrowness" when fit means that I forget I've got it on, even after hours of wear. Hip belt pouches allow me to carry flashlight and snacks for times when I need either (or both). Tall side bottle holders keep even S'well (500ml) bottles in place securely (unless i need to run, in which case I loop an elastic "hair tie" through the relective loop at the top of the holder then loop the other end over the bottle. Now i can run and nothing shifts at all.) Just love the fit and usefulness of this pack as a daypack. it'd be poor even for an overnight pack, but single day use couldn't ask for anything better.
