We Run With the Whole Pack
Running doesn't care how fast you are. Neither do we. Mildly Athletic was built for the full spectrum — from the person who just downloaded a training app to the person who's been doing this long enough to know better and does it anyway. Show up in whatever way works for you. We'll make the shirt.
FAQ's
Do your T-shirts fit true to size?
Yes, true to size. If you're between sizes, go up — a slightly looser running tee is usually the right call, and you can't un-shrink a shirt. See our size chart for details on how to measure for your size.
Shipping & Returns/Exchanges
Orders are processed and shipped as quickly as possible, usually in 1-2 days. Once yours is on its way, you'll get a tracking email. Delivery typically takes 3–5 business days after your order ships, depending on your location.
Not the right fit? Wrong size, wrong vibe, or you just changed your mind — it happens. We offer a 30-day money back guarantee for a full refund or replacement. Reach out through our contact page and we'll sort it out. No lengthy process, no guilt trip.
Washing instructions/Materials
Wash inside out on cold, tumble dry low or hang dry. This keeps the print looking sharp longer than it has any right to.
Our tees are made from a cotton/polyester blend. They're comfortable, hold up to regular washing, and won't fall apart after your third race.
