Partner works in the military and I work in the fitness industry. Wearing metal bands they get dinged up and worp out of shape pretty quickly, not to mention my finger has been nearly degloved once from getting caught in gym equipment. Since wearing the rubber wedding bands, our fingers can breath and the indents on the rings let the sweat escape rather then get stuck under and gather moisture. My partner works around machinery and weaponry so it too reduces the safety hazard making it safe to still wear the bands while on duty, being a black band too it fits with the camo . All in all, highly recommend for both parties.
