Formula 1 Race Car Tee Shirt with Sound by yporque

Shipping calculated at checkout.
Hear the rumble of the engine on this blue cotton tee shirt!  Actual clip of engine warming up then taking off at the start of the race. Exciting!  The sound comes from an attached safe, silicon tab that hangs from the shirt bottom. They press the button for a screaming F1 car!  Tab can easily be removed for 'quiet time'. 

Listen to it here!!

yporqué refers to the question children ask endlessly as they are growing up (¿y por qué? ¿y por qué? ¿y por qué? In English Why? Why? Why?) and the idea of the company came in 2007 from three women with different educational backgrounds (design, advertising and psychology), combining their knowledge to create a children’s clothes brand that, beyond fashion, maintains a very clear concept: a design that focuses on the very people destined to wear the clothes, or in other words, designed for children.
