The Touring Bungee leash is excellent for hiking. It works well in activities such as running, skiing, and bicycling if the dog pulls moderately. The bungee part on the leash is mounted close to the human to avoid a rocking effect. The rest is static, handy if you need to take firm control over your dog. A line of reflective material provides high visibility in the dark. The 13mm wide Touring Bungee comes with an ultra-light and sturdy aluminum carabiner. The 23mm wide versions have a Twistlock carabiner as standard. The carabiner has an automatic lock for more security. The leash will not spin up because the carabiner sits on a swivel. The Touring Bungee series integrates with our Y-leash, the Touring Double. Perfect if you got two dogs.
