The most sustainable wetsuit Billabong make.


Made sustainably, the Furnace Natural made with CICLO® fibers reduces plastic microfiber pollution and plastic accumulation in landfills.

"Made to last" doesn't have to mean "here forever"

CICLO Fibers behave like natural fibers if they end up in the environment. The 100% recycled CICLO Fibres in this wetsuit reduce the persistence of plastic microfibers in our oceans and plastic accumulation in landfills.

CiCLO® additive technology is an easy-to-implement upstream solution that allows synthetic plastic-based fibers to behave more like natural fibers.

CiCLO® fibers, yarns and textiles have been proven effective over the course of several years through reliable scientific data gathered from third party laboratory studies that determine the rate and extent of biodegradation in simulated environments, including seawater, landfills, wastewater treatment plants and soil.

Utilizing proprietary technology to reduce plastic waste in landfills and plastic pollution in our oceans, we leave less waste behind on our journey to create a more healthy, happy planet.
