About the product

Soft, warm, and quietly clever — this sweatshirt wears math like a badge. The front features “Euler’s Constant” in clean type, the Greek gamma symbol, and the beginning digits of the constant arranged with careful spacing. It’s a low-key declaration for anyone who lives for elegant equations: professors grading late-night problem sets, grad students in the math lounge, or lifelong learners who enjoy a subtle intellectual nod in their wardrobe. The medium-heavy cotton-poly blend feels substantial without being stiff. Ribbed collar and cuffs hold shape through repeated washes. Choose small, left-chest, or large-center embroidery accents to add a tactile, handcrafted touch to the printed design. This sweatshirt settles into your everyday rotation — lecture halls, coffee shops, study groups, or quiet evenings with a textbook — and keeps the focus on comfort and cleverness.
