F31.9 Bipolar Disorder: Classic Dad Hat
It's called a dad hat, but you don't need kids, a lawn, or strong opinions about thermostats to wear one. This 100% chino cotton twill cap is unstructured, low-profile, and adjustable — three things we wish we could say about our mental health. The curved visor blocks the sun. The embroidered F31.9 blocks the small talk.
Here's where it gets dangerous: 11 hat colors. 12 thread colors. That's 132 possible combinations. We'd tell you to pick one, but we know how decision-making goes when your brain is running custom firmware. Take your time. Change your mind. Change it again. That's not indecisiveness — that's a curated selection process. You'll land on the right one. Probably. Eventually.
F31.9 — Bipolar Disorder Unspecified. Mood rollercoaster present but the pattern does not land cleanly in one subtype. You know there are highs and lows you just have not gotten a tidy label for them yet. This is the "we know it is bipolar but the details are still arguing" version. The hat is a way to wear that ambiguity without apologizing for being hard to categorize. It is made for people whose charts look like question marks but whose moods are very, very real.
