The peak is black for both branches and all ranks below that of Brigadier. Senior officers wear a single band of goldwire mounted to the peak topside. In most cases army caps feature a black rim around their edge and a green coloured underside. Vinyl is the material of choice on modern made caps. Air force caps reflect the moulded black patent leather pattern used during WWII, exhibiting a tan texured underside, or are made from plastic.
Cap linings are fairly standardised, consisting of a cloth lining with a narrow width leather sweatband. Situated in the lining's crown is a shaped transparent plastic sweat protector displaying the maker's details. Such as Frederich Weichelsdorfer, Sylvia Weichelsdorfer, Litto, or Maria Slama & Sons. The addition of a black HBA dated ink stamp is often found on NCO and recruit caps.
