Key Features

Fully-multi-coated optics assure maximum light transmission resulting in high quality viewing. Every surface of every element is fully coated minimizing internal glare and flare and giving a bright clear view.

Unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronizing the eyepiece movement. This minimizes moving parts and assures these binoculars will function properly and clearly for years to come.

Aspherical lens elements, which are critical in compact binoculars, provide exceptional edge-to-edge sharpness. This assures that items on the edge of your field of view are just as sharp as those in the center.

The UP models are offered in unique, attractive color options that match your personal style.
