The New Standard

At Baseline Theory, we believe the kit you wear should be as enduring as the game itself. We have made it our duty to engineer a collection where traditional aesthetics meet technical, forward thinking materials. By prioritizing GOTS, recycled, certified organics, and ethical labor, we’ve created a line that is soft to the touch, precisely fitted, and radically breathable. For us, performance isn't just about the score it’s about the care we take for the world we play in.

Heritage Style. Social by Nature.

Only The Finest Of Materials

Integrity of the textile is our first serve. Our products are all hand stitched following old world traditions.

Fit For A Tennis Player

Our focus is on combining a refined fit with unparalleled comfort. Distinctive tailoring allows for freedom of movement.

Quality & Longevity

We believe in clothing longevity. It's good for our customers and good for the planet, kit that gets better over time.
