The one that started it all. Our Core Performance Polo is the original Bad Birdie, built on the same promise we started with: serious golf performance wrapped in a design that actually has something to say. Engineered with 4-way stretch that moves with every swing, superior moisture management that pulls sweat away fast, and UPF 50 protection for the long days under open sky. Advanced anti-odor technology keeps you feeling fresh from the first hole to the last, and the Stay-Right collar holds its shape round after round so the polo looks as sharp on hole 18 as it did on hole 1. Lightweight, breathable, and engineered to be the polo you reach for first.
