Zwilling JA Henckels has two styles of Spirit cookware, non stick ceramic and stainless. Both have brushed stainless steel exteriors and a 3 layer tri-ply construction that ensures fast, even heating. The Zwilling Spirit non-stick has an eco-friendly ceramic surface. It does not have PFOA or PTFE. It's also better for the environment because it reduces carbon dioxide emissions during the manufacturing process. Both cookware styles are induction compatible and have a lifetime guarantee from Zwilling JA Henckels.
