Constantly annoyed with thigh poke, key jingle, and damaged pants, the people at KeySmart successfully designed a solution to the bulky key ring. The frame was crafted out of aluminum to be ultra lightweight, and the hardware was milled from stainless steel to survive anything life threw at it. The KeySmart Rugged is KeySmart’s bigger brother. It comes with a built in clip, and has a thicker, more durable build. Expansion pack included.
