Extremely lightweight and compact but outfitted with a powerful magnification for making detailed observations of distant subjects, the green Hawke Optics 10x25 Endurance ED Monocular is an ideal companion for your daily glassing needs that will easily fit in a day bag, hiking pack, camping kit, cargo pocket, or glove box.

Engineered for performance, the Endurance is made with extra-low dispersion glass, a phase-corrected BAK4 roof prism, and fully multi-coated optics to produce color-accurate high-contrast views without distortion or color fringing—so your distant subjects look crisp and clear with excellent resolution. Designed for daily outdoor use in all weather and to make it easy to hold, the Endurance features an ergonomic and slip-resistant armoring with raised ridges to provide a sure and positive grip. The optical tube is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging if the weather turns or it takes an accidental spill in a stream or puddle.
