Mens Core Zero Running Tank - The Unicorn Standard - Boston

Size
Regular price $42.00

Boston is more than 26.2.
It’s the hum of the start line. The roar through Wellesley. The grind up Heartbreak. The right turn onto Boylston when everything in you says go.

The Unicorn Standard – Boston Core Zero Tank was built for that kind of energy — race day in Boston and every long run that leads you there.

Made from our lightest-weight performance knit, this tank feels almost weightless. It’s unbelievably soft with just the right amount of stretch, and the subtle grid texture actively pulls sweat off your skin to keep you cool and breathing easy when the effort climbs.

The classic singlet cut moves naturally with your stride — no cling, no drag — and dries insanely fast, whether you’re pushing the pace or soaking in the crowd.

Light. Fast. Made for big-mile moments.

Boston is earned in a thousand small runs. This is the tank you wear for all of them.
