What is the difference between cork and leather?

The Supakit cat harness comes in two materials - natural genuine leather, and vegan cork 'leather'. They are both equally supple and strong. The only difference between them is their water resistance. The leather harness is splashproof, whereas the cork harness can handle full immersion. So if your cat loves to swim or you live on or around water, we'd recommend opting for the cork harness over the leather!
