You have chosen a shield and a Helmet. Now you must choose a Cuirass to cover your chest and gut. Don't worry about your butt and groin. Greek men didn't normally wear clothes as it was hot and impeded their Schwing, er, I mean, movement. You have two types to choose from. The lighter, and cheaper, Stiff Linen Cuirass or the Bronze bell Cuirass which protects the most.

Stiff Linen Cuirass = 15 GP's

Bronze Bell Cuirass = 25 GP's
