This 8x21 Roamer RC II Binocular is foldable, ultra-compact and stylish. A great companion for short trips or a daily walk: lightweight binoculars that are easy to operate and easy to handle, with convenient center-focus knob for easy focusing and twist-up eyecups with dioptric correction for added viewing comfort. The Roamer 8x21 RC II features a double-axis folding mechanism. Thanks to this design, the binocular height and width are only slightly larger than a credit card when folded. Image quality is excellent, with coated lenses and high-index BaK4 prisms that ensure bright, clear images.
