Do Not Hump Tee

Straight from the rail yard with a twist of humor.

This black heavyweight cotton tee features a bold, vintage-style railroad sign reading “DO NOT HUMP – By Order of the Yard Master.” Inspired by classic freight yard warnings, it’s a nod to railroad history with just the right amount of tongue-in-cheek railroad attitude.

Perfect for the yard, railfans, or anyone who loves a shirt that makes people stop, read, and laugh. Whether you’re on the job, or just hanging out, this shirt delivers rugged workwear vibes with a clever edge.

Crisp white print on our heavy duty work tee. Printed right here in the USA with ink that holds up to real wear, this shirt is made from 7.2 oz of 100% U.S.A. open-end cotton. No blends. No shortcuts. No overseas cheapening. Just a heavy, tough, honest shirt — the way workwear used to be.
