Product Description s best-selling Essentials line balances optical performance and quality construction, offering an affordable way to add a pair of high-quality binoculars to your household, pocket, or suitcase. The handsome, rubber-armored housing not only absorbs shock and protects them from bumps and bruises, it adds in a weather resistance factor should it decide to rain--or snow--at the big event. The Zip focus system allows you to move through the entire focus range in less than a half-turn of the focus wheel--an excellent feature for following fast action. They are especially suited for use over water, snow and in other bright conditions.
