At a glance

Three attachment points are described for front, back and rear-lower leash positions, with different uses suggested for walking and training.
The magnetic Fidlock buckle and S-hook neck opening are intended to make putting the harness on and taking it off easier.
An integrated handle, reflective webbing and logo, and a writable ID field under the handle add practical control and visibility details.
The listing specifies X-Large and a Giant breed-size category. The stated neck and chest measurements are more useful for checking fit than the category alone.
