Does anyone else have “backpack anxiety” for minimal daily carry?

Hey guys, Yes, I used my phone to take the photo, please respect my state-of-the-art paper iPhone 14 replica😂

My daily carry is actually super minimal: keys, earbuds, wallet, maybe some meds. But my biggest anxiety was always the "what-ifs": What if I need to bring a hard drive to the office today? What if I need to grab groceries after work? Because of these rare 5% situations, I used to carry a bulky backpack every day that didn't match my outfit and was 90% empty. It drove me nuts.

I wanted something non-tactical, super low-profile (can even be worn under a jacket), but scalable. So I made this modular setup.

The Base Mode（Image 1）：It sits completely flat. Just for the absolute essentials.

The "Expandable" Mode（Image 2，3）：When I need to carry more (like a hard drive), I can snap on the secondary mesh pouches. The attachment is fully secured for biking/commuting (won't get easily snatched).

See that little blue rolled-up thing in the top right? Packable tote. If I need to buy groceries, the sling stays on my chest, and the tote carries the heavy stuff. Zero need for a daily backpack.（Image 4）

Curious if anyone else suffers from "backpack anxiety" for minimal EDC, and how you guys solve the unexpected grocery run?
