BioThane® Center O-Ring Sport Collar | Waterproof Safety Collar for Hunting & Field Work

Engineered for the rugged demands of the field, the Ulti-Mutt BioThane® Center O-Ring Sport Collar is the essential choice for hunting dogs and upland explorers. Whether navigating thick briars or crossing flooded timber, this collar is designed to keep your dog safe and your focus on the hunt.

The integrated safety O-ring provides critical flexibility. If your dog becomes snagged on a branch or thick brush, the center-ring design allows the collar to pivot and shift, providing the extra give needed to help your dog maneuver and free themselves.

Built from genuine BioThane®, this collar is 100% waterproof and odor-proof. It won't absorb swamp water, mud, or "wet dog" smells, and it remains flexible even in sub-zero temperatures. Unlike traditional leather or nylon, it won’t rot, stretch, or become heavy when saturated.

Field-Proven Features:

• Safety Center O-Ring: Maximizes collar rotation to help prevent hang-ups in dense cover and heavy brush.

• Maintenance-Free: Completely waterproof and antimicrobial—simply hose it off after a day in the field.

• High-Visibility Options: Available in over 26 colors, including high-viz orange and neon green for superior forest and field tracking.

• Custom Engraving: Skip the hanging tags that get caught in the brush; we can engrave your dog’s name and your contact info directly onto the BioThane®.

• Heavy-Duty Hardware: Choose from rust-resistant finishes built to survive seasons of hard use.

From duck blinds to upland ridges, give your dog a collar that is as resilient and reliable as they are. Backed by our Lifetime Warranty.
