The Bushnell Prime X Vault Binocular Pack is the first truly modular binocular harness pack and makes it easy to protect and access your glass in the field. With an ultra-quiet forward open magnetic lid, you can quickly access your binoculars. The lid can act as a shelf when open to keep important items accessible with the internal mesh pocket. The Vaults magnetic closure securely keeps your binos in the pack when closed allowing you to confidently move around in spot and stalk situations and will keep the binos in the pack even when upside down. The Vault also has mesh pockets with an elastic band on both sides for wind checkers and mouth calls as well as a padded slip pocket on the back for your mobile phone or documents. The Vaults modular design can also be used as a stand alone harness without the pack. Prime X Binoculars started out with fully multi coated optics to increase light for a brilliantly bright picture. Then Bushnell used BAK4 prisms to increase brightness even further. To guarantee the weather elements dont get in the way, they gave these Prime binoculars the exclusive EXO Barrier lens coating to shake off water, dust, and debris. Next, they made them IPX7 fully waterproof to inspire confidence in the field. Finally, They gave them a full, transferable, lifetime Ironclad Warranty so you can buy with confidence.
