Some say opposites attract. We say comfort and safety don't have to be opposites in the first place. Engineering based on rock-climbing harnesses for world-class security. Five points of adjustment for a custom fit. And a padded chest plate for comfort. Oh, and one more thing: this harness is fully crash-tested, and yes we used crash test doggies, and yes they're just as cute as you'd imagine. So, safety or comfort? How about the best of both?
