Initially, the long jackets worn by reckless motorcyclist members were mostly white or black, but since the 1980s, colors such as red and purple have become more common.

Additionally, while long lengths were the norm, the increase in color variations led to the emergence of distinct styles that make the body appear slimmer.

The jackets are embroidered with characters that are intentionally phonetic equivalents, making them difficult to read, such as "Kind Regards", along with the group's name.
