Built Different
100% organic cotton. Boxy oversized fit. Rated for 50+ washes without fading or losing shape. Not a fast fashion tee.
⚡
Retro. Always.
Every graphic is designed in-house in Charlotte, NC. Vintage-inspired, never trendy. The tees your kid actually wants to wear every day.
🏡
Family Owned
We started LRT because we wanted clothes unlike anyone else's for our own kids. Every order ships with that same intention behind it.

You'll love these.
