The VRM logo was designed in collaboration by the late (and sorely missed) Si Hands, Visual Artist, and Reid in late 2015, about a year after the club was formed. Si also did the original official Chicago, London, Swiss, and Manchester Rubbermen logos and banners (and these were noteworthy and popular enough, that the standard design is now emulated by practically every other rubbermen group on the planet!)
The Vancouver Rubbermen logo includes aspects of the City of Vancouver flag, including the blue waves representing the Fraser River and the Pacific Ocean surrounding the city, the green representing the great Pacific forests that covered the area prior to development and a traditional Mural Crown, which is an aspect of the Vancouver flag representing city walls or towers and used as a symbolic crown in Roman and heraldic times.
The VRM gas mask, for a Canadian club, is distinctively a modified Canadian C4 gas mask model. This is a typical regional symbol that is significant in almost all other rubbermen club logos.
The tire and font is representative of what you'd find on a standard tire....something that seems to appear in a lot of rubbermen group logos due to the ubiquity of this type of 'rubber' though not the same as latex rubber at all...it just looks very cool!
