You don't have to explain it to an Irish person.

“THAT'S GAS.”

Something funny? That's gas.

Someone telling a ridiculous story? That's gas.

Your mate making an absolute show of himself? Ah, that's gas altogether.

It's short, unmistakably Irish and guaranteed to sound familiar to anyone who's grown up around Irish humour.

Our That's Gas T-Shirt brings this everyday expression to life through chunky, retro-inspired typography, cream lettering and a rich dark outline.

No cartoon characters. No tourist clichés. Just a brilliant Irish phrase doing all the talking.

Why You'll Love It

Instantly recognisable Irish slang.
