Exhaust Sample

Exhaust Sample is for every fresh-out-of-the-schoolhouse boot who learned the hard way that curiosity and diesel fumes don't mix.

In Navy circles, an "exhaust sample" isn't some official maintenance check — it's a rite of passage. New vehicle operators get handed a trash bag and told to hold it over the exhaust port while someone revs the engine, supposedly to "collect a sample." Spoiler: the bag catches nothing but a face full of black smoke. It's not about the vehicle. It's about reminding the new guy he doesn't know squat yet, and he'd better stay sharp before someone else finds a way to fog him up again.

Whether you're wearing it for a drill weekend, a unit reunion, a backyard BBQ with your old crew, or just to remind a buddy who still owes you one from boot camp — this shirt says you survived the initiation and lived to laugh about it.

Keep your eyes open — there's a hidden hare tucked into the artwork, sneaking around like it's dodging exhaust fumes of its own.

There’s a hare hidden in this drawing, drawn into the linework, never stuck on top. It disappears at a glance and shows up when you look closer.
