The towing lines made of vegan BioThane® convince with a whole range of advantages. They are super light and at the same time extremely tear-resistant and robust. Ideal for use in dog training, but also for professional use, eg when tracking or mantrailing. The material is also waterproof and therefore a perfect companion for any weather. The lines do not soak up water or dirt, as is the case with leather or nylon, for example. Even salt water cannot harm the robust material. Dirt can be easily wiped off the fabric. Each Treusin leash is sewn by hand, not riveted, which prevents the material from tearing out.
