Need a pair of binoculars that are light enough to take anywhere, yet versatile enough to deliver reliable performance whether you're in wet or dry conditions?

The Pentax 8.5 x 21 Papilio Binoculars might just be the one for you. A powerful 8.5X magnification brings objects 8.5 times closer than your naked eyes can see. The large 21mm objective lenses gather more light, making a brighter image. At a mere 10.2 ounces, these versatile binoculars are suitable for backpacking, birding, sports events, stargazing, and pretty much any activity you might reasonably want binoculars for.

Only you can decide if these are for you.
