Description
The Hawke Nature-Trek 10×42 is the kind of all-around binocular that earns a permanent spot in your pack. It pairs 10x magnification with 42mm objectives, which is a sweet spot for pulling in distant detail while still gathering enough light for those early mornings and shady tree lines. The heart of the optic is Hawke's System H2 build, using phase-corrected BaK-4 roof prisms and fully multi-coated lenses to keep images bright, high-contrast, and true to the colors your eyes expect to see.
What the Nature-Trek 10×42 Brings to the Field
A 4.2mm exit pupil and 13mm of eye relief make these comfortable to look through for long stretches, and the twist-up eyecups with position stops let eyeglass wearers dial in a clean, full view. The focus wheel runs the full range in about two turns, so going from a warbler at your feet to a ridgeline a few hundred yards out happens fast. Close focus drops to around 6.6 feet, which is handy if you're into butterflies, dragonflies, or anything that lets you get close. Field of view runs about 304 feet at 1,000 yards, giving you plenty of room to track movement.
Built to Take a Beating
The Nature-Trek chassis is shock-resistant polycarbonate wrapped in textured green rubber armor, so it stays light in the hand and grips well even when your fingers are cold or wet. At roughly 22.5 ounces, it won't wear on your neck over a full day out. The tubes are nitrogen-purged and O-ring sealed, making them waterproof and fog-proof when the weather turns on you.
Whether you're glassing for deer, chasing birds, or just watching the world at a ballgame, this is a versatile, no-drama pair that punches above its size. It also carries Hawke's No-Fault Lifetime Warranty, which speaks to how much they stand behind it.

Frequently Asked Questions
Are the Hawke Nature-Trek 10×42 binoculars good for birdwatching?
Yes, they're a solid pick for birding. The 10x magnification pulls in distant birds while the fully multi-coated BaK-4 optics keep colors natural and details crisp. The close focus of around 6.6 feet also lets you enjoy birds and insects that come in tight.
Can I use the Nature-Trek 10×42 with eyeglasses?
Absolutely. The twist-up eyecups have position stops and there's 13mm of eye relief, so you can back them off to get a full field of view while wearing glasses or sunglasses. Just twist the cups down and dial in the spot that works for you.
Are these binoculars waterproof?
They are. The Nature-Trek tubes are nitrogen-purged and O-ring sealed, making them fully waterproof and fog-proof. That means you can keep glassing through rain, humidity, and quick temperature swings without internal fogging.
How heavy are the Hawke Nature-Trek 10×42 binoculars?
They come in at about 22.5 ounces, which is comfortable for a full-size 10×42. The polycarbonate chassis keeps the weight down without giving up durability, so they won't drag on your neck over a long day in the field.
