Premium ED glass for stunning visuals
High-quality ED (Extra-low Dispersion) glass minimises chromatic aberration, ensuring vivid colours and razor-sharp images. The prisms made from BK-7 glass feature a PXA phase coating that enhances sharpness and contrast, while the fully multi-coated lenses maximise light transmission to deliver bright, clear views, even in low-light conditions.
Built for the great outdoors
Designed to perform in any weather, the Chisos 8x25 is equipped with a waterproof housing that protects the optics from moisture. Its durable rubber armour provides a secure grip and shields the binoculars from impacts and scratches.


Perfect for glasses wearers
Glasses wearers can also enjoy a full field of view with the Chisos 8x25. Twist-up eyecups ensure comfortable use, while the built-in dioptre adjustment allows the binoculars to be customised to suit individual eyesight needs.

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.
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.
Weatherproof design

Watertight design

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.
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.
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.
Bright images, even on dark days

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.
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.Technical Data
