Sport Rat Shirts

Rats competing with far more enthusiasm than technique — running, swimming, soccer and more.

Sport doesn't have to mean matching lycra and serious faces. Our sport rat collection is for the rec-league heroes, the treadmill warriors, and the athletes who take the workout seriously and themselves not so much. Each design starts as a hand-drawn sketch — no clip art, no templates — before it becomes a soft, breathable rat t-shirt built for actual movement.

Whether you're chasing a marathon PR, taking a cricket ball to the shin and calling it “close enough,” rollerblading through the neighborhood in full chaos-gear, or doing laps until your arms give out, there's a rat character here that gets it. These aren't generic athletic graphics pulled from a stock library — they're original characters with personalities, drawn specifically for people who find sports a little bit ridiculous, in the best way.

Gym rat is practically our whole personality. If you've ever shown up to leg day running on pure spite, or signed up for a 5K and immediately regretted it around mile two, one of these tees is basically a mirror. They're printed in a vintage ink and watercolor style on soft, durable cotton, sized from XS to 5XL so the whole team — or the whole family — can match.

What is a “gym rat” shirt?

A gym rat shirt is a funny, relatable t-shirt for people who live at the gym (or wish they did) — our versions feature original hand-drawn rat characters instead of generic gym slogans.

Are these shirts good for working out in?

Yes — they're printed on soft, breathable cotton in a relaxed, true-to-size fit that's comfortable for workouts, runs, and everyday wear alike.

What sizes are available for sport rat shirts?

Every sport design comes in a wide XS–5XL range, so teammates, training partners, or family members of any size can match.
