Boston is more than 26.2.
It’s the quiet focus before the start. The surge of cheers through Wellesley. The grind up Heartbreak. The final turn onto Boylston when you find one more gear.
The Unicorn Standard – Boston Core Zero Women’s Tank was built for that kind of day — and every mile that builds toward it.
Crafted from our lightest-weight performance knit, this tank feels nearly weightless. It’s unbelievably soft with effortless stretch, and the subtle grid texture works to pull sweat off your skin while staying ultra-breathable. When the effort rises, it keeps you cool and dries insanely fast.
The classic, full-length, streamlined cut with a racerback gives you a singlet designed to move with you — never against you. No distractions. No cling. Just smooth, fast comfort from first mile to finish line.
Light. Fast. Ready for big-mile moments.
Boston is built in the training. This is the tank for all of it.
This tank fits true to size.
Cold wash separately before first use. Tumble dry low. Do not iron or bleach.
92% polyester 8% spandex
Our most premium performance fabrics. A knit, engineered to let heat out and wick sweat away quickly. Bonus points for beings softer than a pillow.

"Cute flowered print and an excellent light fabric for hot summer runs. Size up if you like a loose fit."
"Lived up to my expectations of a cute tank for my husband. Fit well"
"Super excited to wear this for my upcoming spring marathon. Perfect loose fit and lightweight. Bought a large and fits true to size."
"First time trying the tank, love the material, I did size up based on other reviews and I like the fit."
"Love the tank sized up based on other reviews but i dont think it was needed couldve definitely ordered my normal size. But still the coolest tank i own now."
"Great tank and style. Fit is tts and perfect."
"Full disclosure: I don't really spend this amount of money on a single article of recreational clothing. I tried this because I like the other things I've received from this brand, and enjoy the humor of making fun of my own party pace. I like this shirt so much that I will be buying more in different patterns. I am a woman who enjoys a looser/boxier fit on sleeveless shirts, so I purchased the men's version. It is the platonic ideal of exercise shirts for my tastes. Loose enough to feel like I can move in it without swimming in fabric, good coverage, and incredibly comfortable. It is delightfully lightweight and doesn't have that odd "sports fabric" texture that other moisture-wicking clothes do. It has held up well in the laundry well so far, without the decals peeling. Overall, very pleased with this purchase and will be back."
"Perfect fit. Got lots of compliments"
"It’s a beautiful tank (I got turbo turtle). High quality! It is cut really slim though, so be aware. I’m between a medium and small, got the medium and you’ll definitely see it if I have breakfast in the morning. If I got another I would probably size up to large to have some breathing room. 5’9”, 118lbs, 34B for reference."
