Kono's

Konos is a conical Macedonian helmet worn in combat during the Hellenistic era. Its pointed shape is similar to the pilos helmet that is placed underneath a konos as an interior protector. Although close in design, a pilos helmet has a small visor around the opening and a konos helmet is created to have a thin brim protruding from its base and closely fits around the warrior's head.
