Our Martingale Nylon Dog Collar is a heavy duty, reflective, locking, nylon clasp martingale dog collar.  It has many features not normally found in martingales.
The collar is 2mm thick and very strong and made for the largest of dogs.  Its quality nylon webbing contains reflective stitching for improved nighttime visibility.  It features a lockable nylon clasp which prevents an accidental releasing of the latch when grabbing the collar.
