Sightmark has released the Solitude XD binoculars, a line built around upgraded ergonomics and XD extra-low dispersion glass. The optics feature fully multi-coated lenses and phase-corrected dielectric prism coatings that transmit more than 85% of available light, supporting visibility in low-light conditions such as dawn and dusk. Both the 8x42 and 10x42 models include Bak-4 roof prisms and nitrogen-filled, IPX7-rated construction to resist fogging and moisture in wet or unpredictable weather.
