That s why Bushnell had the foresight to build the H20 series of binoculars which are O-ring-sealed and nitrogen-purged to complete lock out moisture should you spill water on the housing take your binoculars overboard or simply run into foul weather along the way. The H20 binoculars feature rubber armoring with Soft Texture pads to give you a sturdy grip in slippery situations.
