Mainsail Tee

Nautical-inspired summer tee with bold contrasts



The Mainsail Tee is a nautical-inspired summer tee with smart contrasts in both color and texture that mimic the horizontal and diagonal shaping of a ship’s mainsail. And, like a mainsail, it’s an essential (at least as far as summer wardrobes go).
