Sport Rat Shirts β€” Gym Rat & Athletic Rat Tees

From marathon mornings to pool laps, these hand-drawn rat characters bring a little chaos to every sport. Original hand-drawn designs for runners, swimmers, skaters, and anyone who's ever said "close enough."

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. Every design is DTG printed on a premium unisex tee made from Airlume combed and ring-spun cotton, available in black or white, sized from XS to 5XL so the whole team — or the whole family — can match, and every order ships free within the USA.
