To fit its durable leash, the COLLAR Company launched Evolutor, a durable collar made of COLLARTEX material. It is sewn with KEVLAR thread and features aerospace aluminum alloy hardware. The collar, as well as the leash, can withstand 500 kg. One size fits all (2 to 70 cm). The collar is easy to wash and doesn’t slip from hands. Its buckle is perfect for engraving and can be unfastened with one motion.
