This heavyweight cotton tee carries a vintage, hand-carved emblem that reads “IH2I” on the front and printed black and white line art on a square on the back. The relaxed, slightly oversized silhouette and durable 7.5 oz USA-spun cotton give it a lived-in, dependable feel. This is the kind of shirt you reach for when you want to make a quiet, clever statement. Wear it on long drives, at late-night meetups, or while tinkering in the garage; it sits comfortably over layers and holds its shape wash after wash. The textured emblem and deep colorway invite conversation without shouting, fitting effortlessly into a wardrobe that values authenticity and subtle, science-forward humor.
