The Garmin Universal Collar Strap is a polyurethane-coated collar.  It is rugged and water resistant, just like the original collar that came with your dog tracking device. The 27-inch nylon collar has a nickel plated square buckle and collar keeper and has holes spaced to fit most dogs.

Garmin mini collars use the 3/4" wide strap and the Garmin standard sized collars use the 1" wide strap.
