This vintage-style oversized T-shirt features a unique muscle pump graphic celebrating exercise-induced hyperemia from intense resistance training. Made from 100% combed cotton with a 260 g/m² fabric weight, it offers a relaxed oversized fit with raw edge hem, drop shoulders, and durable double-stitched construction. Wash on the reverse side with neutral detergents, avoid soaking, sun exposure, and bleach, and tumble dry at low temperature; slight color floating may occur during initial washes.
