Hawke Sports Optics' green 10x42 Nature-Trek Binoculars feature silver-coated BAK4 roof prisms and anti-reflection fully multi-coated optics to produce a versatile and capable optic that produces bright and clear images with accurate color rendition. Coupled with the optical features are 42mm diameter objectives which give the binoculars very competent low-light performance. This combination of optics and objectives make the Nature-Trek binoculars ideally suited for most outdoor activities from hunting, to birding, to sporting events.

Complementing the optical performance are construction details that make the binoculars durable and comfortable to use. Their durability starts with a lightweight, impact, and corrosion-resistant polycarbonate chassis that is protected by green rubberized armor. The armoring is textured to give it a non-slip grip especially in cold and wet conditions. The optical tubes are nitrogen-filled and O-ring sealed to be water and fogproof - especially in extreme weather conditions. A right-eye diopter adjustment allows the binoculars to be customized to most people's needs, and twist-up eyecups means they can be comfortably used with or without eye wear.
