Sprint and catch that train. Bike to your next meeting. Pour that wine with aplomb. Thanks to four-way stretch and a stain-resistant finish, the Proof Performance Oxford rises to every occasion. A 21st century take on the traditional Oxford shirt, this button-down combines the strength of nylon with the comfort of cotton to create a shirt that looks and feels like your favorite everyday Oxford, but moves like a performance tee to keep you cool, comfortable, and on-the-move all day long.
