Race bib pinned on, water bottle in hand, and a face that says he's already regretting mile one β this rat is running anyway.
The Marathon Runner Rat Tee is an original hand-drawn design for anyone who's signed up for "just a 5K" and immediately spiraled into full marathon training. Our rat wears his race bib with pride, water bottle in hand, giving off equal parts determination and mild panic.
It's a natural gift for runners, race-day teams, or the classic "gym rat" who's at the track before sunrise. Printed in black & white on a soft, breathable cotton tee, it's built for the finish line and everyday wear alike. Sizes XSβ5XL, free USA shipping.
Every Silly Rat Collection tee is a premium unisex t-shirt made from Airlume combed and ring-spun cotton, giving it a soft feel that holds up wash after wash. Each design is DTG (direct-to-garment) printed for a crisp, long-lasting finish, and available in black or white, sized XS to 5XL for a comfortable, everyday fit. The cotton is eco-friendly, and since fit can vary slightly by color and size, it's worth checking the size chart on the listing before ordering.
