As its name attests, this nifty compact binocular performs like a champ in any weather conditions. It is nitrogen-purged and O-ring sealed for 100% protection against water and internal lens fogging, which will be welcome news to boaters, kayakers, hikers, and backpackers. Its 8-power optics feature high-grade BAK-4 prisms and antireflection coatings for great light transmission. The Weather Worthy has a bright yellow, can't-miss-it rubber covering so you'll always know right where it is. Black grip mats with finger grooves provide a secure, comfortable grip. Includes padded neck strap. One-year limited warranty.
