Calling all coders, tech lovers, and geeks with a sense of humor! This Urban Backwoods long sleeve tee features a fun, bold print that says \What Part of Binary Don't You Understand?\ – a great conversation starter. It's made from 100% semi-combed cotton, so it's soft, breathable, and has a nice heavyweight feel (190 g/m²). The classic regular fit is comfy for everyday wear, and the print uses high-quality inks that stay bright wash after wash. Just note: it uses European sizing, so check the size chart before ordering. Whether you're heading to a comic-con, a casual Friday at work, or just hanging out with friends, this shirt lets you show off your nerdy side in style. It's preshrunk, so it won't suddenly become a crop top after washing. A cool, well-made tee for anyone who loves tech humor and wants something durable and comfy to wear.
