This wrist-mounted mirror is made from a plant based bioplastic. It is used to increase your situational awareness, keep an eye on your buddy or team, and self inspect your equipment. The rear can be unscrewed to replace the reflective surface. The bungee is supplied untied on one end so that it can be sized to your hand. The reflective surface is convex, allowing for a wide field of view. The mirror is low profile to reduce the risk of entanglement or reduced dexterity.
