Tasco's compact 8x21 Essentials Compact Binoculars are an ideal instrument that brings the action up-close without taking up a lot of room or adding excessive weight. Anti-reflection fully multicoated optics maximize the light coming into the 25mm objectives while minimizing light loss. A dual-hinge design enables the optical tubes to be folded tightly under the bridge for an ultra-compact form factor that allows them to fit easily into a pack, coat pocket, or glove compartment.
