Stay Adventurous
A durable dog collar made from repurposed climbing rope — built for everyday wear, comfort, and years of adventure.
Why You'll Love It
Climbing rope is designed to hold thousands of pounds, making it incredibly strong and durable. By repurposing retired rope, we give it a second life while creating gear built for everyday adventure.

Perfect For
Your dog wants sustainable gear too! Better for the planet and better for our community. A portion of every purchase helps support environmental and community projects through Project Merrimack.

Adventure together!
**Please note: We recently changed the sizing of our collars, so be sure to measure around your dog's neck before selecting your size - even if you've purchased before.
Based in Lowell, MA., home of the American Industrial Revolution and textile industry in the USA, our designs honor the legacy of this great city, but do so in a more modern and responsible way
