In addition to the XP Optics, is a new high-tech optical coating on both the objective and eyepieces called "NANO Protection". This new coating repels water and moisture off the lenses leaving them clear of water or moisture. Like windshield wipers for your binoculars, you won't ever have to wipe them clean of moisture. The secret lies in a unique permanent molecular bonding substance that makes the lenses so smooth, that absolutely nothing adheres to them. Each Commander XP is hand-built to be mil spec waterproof and shock resistant.
