This relaxed, garment-dyed tee wears like an old favorite from the moment you put it on. Heavyweight ring-spun cotton gives it structure while the post-construction dye and soft texture age beautifully with each wash. The front features a bold, typographic “REFERENCE PLANE” headline above a subtle, schematic-style diagram — a look that nods to engineering boards, drafting tables, and late-night problem solving. It layers easily under a flannel or stands alone with jeans for a low-key, thoughtful outfit. Expect a lived-in hand, muted color depth from the dye process, and a cut that sits comfortably through the shoulders and chest without clinging.
