This silcon-like material is super soft and a nice change from the rope type leashes. The clip on the end opens by pressing on the sides and then closes securly around the collar, I have two bigger dogs that love to pull and this leash makes me feel safe that they aren't going to break the clip on the end. I love the vibrant green color of the leash, to make sure people can really see it in the day time. The leash is very strong and durable.
