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 slightly slim. If between sizes we recommend sizing up. Sizing Chart Located Here.
