My scenario is a bit different, including underwear 
This is my usual setup since I go out in nature a lot and stay usually over the weekend (unwinding from work) mostly.
- NFC Ring for access and other stuff (until and IF my NExT and Spark chips get thru customs)
- Garmin watch for health and oxygen tracking and NFC Payments
- Samsung earbuds that let me listen to music, but also hear whats around me at the same time (almost like superhearing)
- Finally, a xd tech backpack with solar panel, a powerbank and wireless charging for my phone and other devices.
