Reworked the overnight bag to a light, grab-n-go sub-load to toss into a bag if/when needed. Contained in an Eagle Creek Pack-It Cube:
T-shirt and skivvies, ranger rolled for compactness
Merino wool hiking socks
Toiletry kit with toothbrush, toothpaste, floss
Simple, practical and inexpensive to throw together...clothes you've got lying around. Just pick 'em out and set 'em aside.
