They tried to bury him with zoning codes and council hearings, but Marvin Heemeyer came back with something a little sturdier: a tank on treads.

June 4, 2004. Granby, Colorado. A date that’s burned into the minds of anyone who’s ever felt the searing injustice of local bureaucracy. While most of us just grumble and pay the permit fees, Marvin Heemeyer, owner of Mountain View Muffler, decided to up the ante. And by “up the ante,” we mean he fortified a Komatsu D355A bulldozer with 30 tons of concrete, steel plating, and a whole lot of righteous fury.

The man turned his welding skills into warcraft, transforming a piece of heavy machinery into an unstoppable force of pure "enough is enough" energy. Buildings fell. Power players panicked. The whole world watched as the Killdozer’s path of destruction made headlines and inspired debates on government overreach, property rights, and just how far one man can be pushed before he starts pushing back—literally.

The Heemeyer’s Mountain View Muffler Tee is a wearable reminder that when life boxes you in, sometimes you’ve gotta bulldoze your way out. Made from 100% ring-spun cotton, this garment-dyed beauty is as durable as Marvin’s resolve. It’s pre-shrunk, heavyweight, and just structured enough to keep you looking sharp while staying comfy. And yes, it’s got a pocket—because every rebel needs a spot to stash their notes, nuts, bolts, or whatever’s fueling your next act of defiance.

Product Features:

• 100% ring-spun cotton — As tough as a grudge, but way softer. 
• Fabric weight: 6.1 oz/yd² (206.8 g/m²) — Heavy-duty enough to handle a hard day’s work.
• Garment-dyed, pre-shrunk fabric — No shrinking. No surprises. Unlike your last property assessment. 
• Relaxed fit — Because stress fits like a straitjacket. 
• Twill-taped neck and shoulders — Reinforced for strength. No weak points here. 
• Double-needle armhole, sleeve, and bottom hems — Built to outlast your patience with city planners.
• Single-needle left chest pocket — For carrying small tools, big ideas, or the receipts. • Signature twill label — Matches the color of the garment, so even the tag’s on brand.

This tee’s for the grinders, the welders, and the men (and women) who’ve had their backs against the wall and decided to push back—hard. Whether you’re walking the shop floor, working in the garage, or just out running errands with that simmering “not today” energy, the Heemeyer’s Mountain View Muffler Tee has your back. Literally.

Wear it. Own it. And if anyone asks, "What's the story with that shirt?" you’ll have one hell of a tale to tell.
