The Ultravid 10x25 Binoculars effortlessly combine a unique compact form-factor with Leica's renowned optical excellence. They consist of P40 phase-corrected BAK4 roof prisms, the proprietary HighLux system, and HDC fully multi-coated optics. In essence, this ensures a bright, natural, and colour-neutral image that guarantees to level-up your observational experience. Whether you are out nature spotting, birdwatching, exploring the city, or even sitting in an auditorium watching a theatre show, the Leica Ultravid 10x25 Binoculars are the ones for you. As they are so compact, you can easily pocket them or pack them away in your bag for on-the-go adventures. This is aided by the dual-hinge system, which allows the optical tubes to fold fully beneath the closed bridge; further designating a wide interpupillary distance adjustment range. They are also O-ring sealed and nitrogen-filled to ensure fog and waterproof functionality, as well as being fully submersible to a depth of 5m.
