👋 Hello from Team TK

Surprise! No big corporation here. We're a grassroots operation at the base of the Eastern Sierra mountains. TK is a woman owned and run company that started in 2016 because we got tired of sports bras that don't fit! Our mission is to redefine the way clothes fit and function, so you can get out there and be your outside self.
