At Rusty we were sick of seeing the big players in wetsuit production continually using harmful petrol chemical-based neoprene in their ranges just to cut costs. We developed our ECOPRENE foam, made from 100% limestone-based foam providing the lightest, comfiest and strongest foam on the market. We didn't stop there with our search for the eco-friendly / performance wetsuit. The range is constructed from eco-friendly yarns and jersey as well as water-based glues and laminates.
