About the product

Soft, midweight crewneck sweatshirt embroidered with Euler’s identity across the chest — e^(iπ) + 1 = 0 — and a small subtle logo beneath. The black fleece body and ribbed collar give a clean, minimalist canvas that lets the math-centered design speak. Wear it to late-night study sessions, coffee-shop discussions, or casual lectures; it settles in like a quiet, confident companion. The fabric has a cozy hand without feeling bulky, and thoughtful details — tear-away label, tubular knit with no side seams, reinforced double-needle stitching — keep it comfortable and long-lasting. For people who love elegant math, plain style, and durable everyday wear, this sweatshirt blends clarity and comfort into one understated piece.
