Billabong

Billabong A/Div (Adventure Division) is an outdoor- and adventure-oriented offshoot collection officially offered by Billabong, with products marketed under the A/Div designation. It is primarily composed of items such as Surftrek-style pants and functional jackets, as well as pieces featuring materials and specifications intended for use on trails and in cold-weather environments. Its use cases and functionality differ from the main surf/swim line, making it a technical sub-line that complements the brand’s outdoor range.

Billabong Furnace is a high-performance family name used by Billabong for its wetsuit and cold-weather product ranges. Centered on wetsuits that emphasize high thermal insulation and sustainability under line names such as “Furnace Natural,” it also spans related cold-weather apparel and boots. It is a sub-line serving a specialized area of surf products, with a focus on wetsuit insulation and materials technology.
