Clothing and style are important aspects of heavy metal culture, used by musicians and fans to identify with the broader values and norms of the subculture, and to communicate difference from mainstream culture. Denim and leather garments are fundamental to metal wardrobes, with band t-shirts worn nearly universally to signify particular metal preferences. For serious metal fans, battle jackets offer a unique way to demonstrate musical taste and dedication to metal. A battle jacket is a customised denim jacket (usually with the sleeves removed) embellished with band patches, badges, studs, hand-painting and other additions. Jacket customisation has been practised by fans for nearly as long as heavy metal has existed, and thrives in contemporary metal subcultures, bolstered by online jacket forums and patch trading opportunities. Historically, battle jackets can be connected with WW2 bomber jackets and custom motorcycle patch vests. For fans, battle jackets offer a way to externalise their allegiance to metal and to reinforce a sense of ‘outsider’ status. The jackets also carry highly personal meanings for their wearers and help to articulate a sense of self that extends beyond recreational fandom.
