Improving on a best-selling, first-of-its-kind favorite like the Bino XR proved to be a tall task. Thousands of five-star reviews can make it easy to just relax. That&';s just not our style. Focusing on functional updates, the Bino XR Pro features a larger, easier-access binocular compartment, a streamlined design, and the addition of our accessory-ready side wings. Your all-in-one binocular/rangefinder case just got better.
