The Bushnell Trophy XLT 10x 42mm Binoculars (Special Bone Collector Edition) offer world-class optics and superior durability. With light transmission, clarity and ruggedness as top priorities, we built the ultimate hunting binoculars. These powerhouse binoculars have fully multi-coated lead-free optics and BaK-4 prisms that work in tandem to deliver ultra-bright, razor-sharp images through the most critical periods of game movement. The tough, streamlined Dura-Grip rubber-armored housing is O-ring sealed and nitrogen purged for 100% waterproof/fog proof dependability. Soft-touch thumb grips further improve handling ease, and the objective lenses are protected from the elements by flip covers. This great binocular also comes with a Deluxe Bingo Harness that is the perfect solution for unparalleled comfort and performance when wearing your optics. It keeps the weight off of your neck and keeps your Trophy XLT binos front and center no matter where the hunt takes you.
