I was looking for a climbing rope leash that wasn’t ridiculously expensive for quite some time, and I happened upon a shop while traveling and found these Mountain Dog leashes! I love how thin the one I have is, and I tested it out on a hike with my dog’s ruffwear harness and it performed perfectly! It’s lightweight but very strong (my dog is a 60lb poodle) and handled him jumping over logs and stuff really well. I definitely hope to buy more but I would like the thin leash to come with a carabiner instead of the normal clip (would be optimal). I think my next purchase will be the multi-use leash! I’m so glad I found you Mountain Dog!
