The UpClose G2 8x21 Roof Binoculars from Celestron are lightweight, 8-ounce binoculars with a closed-hinged bridge design. At less than 4 inches, they are a prime candidate for easily mobile binoculars that leave no excuse to be caught without some magnification for that surprise situation. The water-resistant, rubber-covered, aluminum body adds an added level of worry-free use from rough handling and use. The sure grip furnished with thumb indents and finger ridges are a welcome feature allowing a firm nonslip hold. Just another reason to make sure that these binoculars get taken along.
