Leupold Wind River is putting birders on notice: start getting excited about the Leupold Wind River Katmai Series binoculars right now. Why? They give you all the performance of a full-size binocular in a compact package that's lightweight, and easy to carry or pack. The key is the Katmai's 32mm objective lens and L-coated prisms that work together to transmit a greater amount of light to your eye than traditional compacts, which usually employ a much smaller objective lens.

L-coated prisms and fully multi-coated lenses – L-coat™ is Leupold’s own 64 layer, anti-reflective coating. Applied to the prisms, it’s incredibly effective in improving light transmission. Multiple lens coatings also work to enhance light transmission and brightness.

Ergonomic, compact design makes the Katmai’s easy to carry or stow in a cargo pocket. 

Twist-up eyecups and generous eye relief for comfort and ease of use, even with glasses.
