Helmets and methods for manufacturing a helmet are described. An example helmet includes an upper helmet component having a shell and a shock absorbing liner and further having a lower helmet component having a shell and a shock absorbing liner. The shock absorbing liner of the lower helmet component has an angled interface portion to which the upper helmet component is attached. A vent sill is attached to the shock absorbing liner of the upper helmet component and a vent shutter is slidably attached to the vent sill. An example method include forming a first in-mold component having a shell and shock absorbing liner and forming a second in-mold component having a shell and shock absorbing liner, the shock absorbing liner having a seamless headform.
