I posted previously about adding BioThane leashes to our product line. We now have a variety of widths, thickness, colors and length. Most recently we have added camo and a super heavy. All of these stay flexible in the cold as well.
All of these leashes are made by me at the time of order, hand cut and hand riveted. No machines involved. Take a look. Biothane is great if you and your dog spend a lot of time getting dirty LOL. Cleans up quickly with water.
