Crystal-clear images thanks to premium ED glass

The outstanding image quality is a result of high-grade ED glass (Extra-low Dispersion), which minimises chromatic aberrations for natural, pin-sharp views. The BaK-4 prisms feature advanced PXA phase coating for exceptional sharpness and rich contrast. Full multi-coating across all lens surfaces maximises light transmission, delivering bright, clear images even in poor lighting conditions.

Built to withstand the elements

The Chisos 10x42 thrives in any weather. The fully waterproof housing keeps moisture at bay, while the durable rubber armouring provides a secure, comfortable grip and protects against bumps and scrapes.

Icon for ALPEN BAK4 roof prism

Crystal-clear images with premium quality optics

Unlike the standard BK-7, the optics are made from BaK-4 glass (barium crown glass) that produces even sharper and brighter images. The high-quality BaK-4 glass optics are used in all ALPEN Optics products sold in Europe.
Icon for ALPEN fully multi-coated lenses

More light for clearer images

The optics are fully coated with a premium multi-layer coating, which increases the light transmission to up to 95% to produce stunningly bright images.
Icon for ALPEN fogproof optics

Weatherproof design

The binoculars are filled with nitrogen, which prevents the inside of the lenses from fogging up and obstructing your view during abrupt changes in temperature.
Icon for ALPEN waterproof optics

Watertight design

Thanks to the waterproof housing that prevents liquids from reaching the inside of the optics, you don’t need to worry about heavy rain or dropping the binoculars in a puddle.
Icon for ALPEN twist-up eyecups

Easily adjustable for glasses wearers

Thanks to the twist-up eyecups, the design is also suitable for people who wear glasses. The distance between your eyes and the lenses can be easily adjusted to allow you to see the complete field of view.
Icon for ALPEN diopter adjustment

Fine tune to your vision

The built-in dioptre adjustment allows you to quickly adjust the optics to your vision and compensate for differences between your left and right eyes.
Icon for ALPEN tripod adaptable design

Tripod connection thread

Thanks to the tripod connection thread, the optics can be quickly mounted on a tripod so that you can enjoy shake-free images of animals or nature.
Icon for ALPEN HR metallic coating

Bright images, even on dark days

The binoculars feature a premium HR metal prism coating that significantly increases the light transmission and lets more light into your eyes. The result: bright and impressive images, even in challenging light conditions.
Icon for ALPEN PXA phase coating

Special coating for more clarity and contrast

Thanks to the first-class PXA phase coating, these binoculars allow you to take in every detail in crystal-clear, high-contrast images.
Icon for ALPEN nitrogen purged optics

Nitrogen filling

The temperature can change rapidly when you’re out in the wild. To prevent the lenses from fogging up on the inside and obstructing your view, the optics are filled with nitrogen.
Icon for ALPEN ED glass optics

Stunning true-colour images

The high-performance ED glass significantly reduces scattered light and prevents chromatic aberration, enabling you to observe true-colour, brilliant images of wild animals, landscapes and more.
