What’s 100% badass, 100% vegan, and 100% waterproof? These colorful spiked collars from Lithuanian brand Sighthound Squad! Made from BioThane, a type of PVC-coated webbing the folks at Sighthound Squad refer to as unicorn leather “because it’s basically a magical substance and vegan approved” — it has the look and feel of leather, requires zero maintenance, and is stronger than leather, nylon, or other materials often used for leashes and collars. While we’re big fans of the studded collar look, the Sighthound Squad also offers a variety of other colorful styles. Take a look at their complete collection available on Etsy.
