Embroidered 'S = k ln W' Bucket Hat — Thermodynamics Statistical Mechanics Dad Hat

Soft, lived-in cotton twill shaped into a casual bucket hat with subtle embroidered detail. Lightweight and breathable, it sits low on the crown and keeps the sun off your face while adding an easy, thoughtful accent to simple outfits. Wear it on slow weekend mornings, on city walks, or folded into a bag for unexpected weather. The understated stitched patch reads like a quiet inside joke — something your friends will notice without shouting. It matches layered tees, linen shirts, and vintage denim, bringing a relaxed, intentional finish to everyday looks.
