This bowler hat is dome-shaped and sports a curved brim, plus a black sweatband. It is made of a hard, dark felt and when worn, provides a single point to Endurance. It cannot be modified with ballistic weave.
Two can be found inside Monsignor Plaza: One on the ground by a skeleton holding a Jangles the Moon Monkey doll near the elevators, and one on a shelf inside the stationery department.
Two are on the second floor of the Boylston Club, one on the head of a skeleton on a couch facing a coffee table and another on the floor across the room near the windows.
PC When equipping the Bowler on Handy-type robot companions, then removing or unequipping it, the hat may remain visible on the 3D model of the companion.[verified]
