Built for the trail with gentle control. Our Adventure Style Mountain Flat Weave Martingale Dog Collar uses authentic mountain climbing rope, woven flat in our Mountain Sunrise pattern, finished with a YKK polyacetal side-release buckle and welded steel D-ring. The limited-cinch martingale design tightens only when your dog pulls, then releases - safe, no-slip restraint without the harshness of a choke chain. Ideal for hikes, training, and dogs with narrow heads. Hand-built in Colorado from materials trusted on the wall.
