The Non-Aggression Principle states that any kind of harm is wrong, and implies that people can do as they wish as long as it doesn't harm anyone. Wear this shirt and play a joke on people who step closer to read what's written on it. Their invasion of personal space should not go unpunished!

"If you can read this, you're violating the Non-Aggression Principle."

For those on a tighter budget, here is the economy tee - still very soft and comfortable to wear, but also easy on the wallet. A great shirt you'll be happy to throw on and hang out in all day, while showing everyone your liberty-themed beliefs.

• 100% Combed & Ringspun Cotton: light and extremely soft, you'll wear it all day, every day
• Classic Fit: relaxed, chill style
• Double-Stitched Neckline and Sleeves: durable to resist dissenters trying to rip it apart
• Pre-Shrunk: the washing process won't tax 10% of your shirt
• Showcased Design: show your beliefs and unite libertarians everywhere
