XP engineering for rough handling
Vortex knows there will be times when it's just plain hard to keep a handle on things ... that's why the Vipers feature XP engineering. This design anchors internal prisms in place, in spite of rough handling, for years of exceptional viewing. Let it rain. Let it snow. Let the wind blow up a dust storm. Nothing gets past the 8x42 Viper. These binoculars are absolutely dust proof, fog proof, and waterproof!
Complete waterproof protection keeps dust and water out of the optical system with tight O-ring seals.
Complete fogproofing of internal lenses presents clear views in spite of sudden temperature changes because of nitrogen purged optics.
Ribbed rubber armor ensures a solid, comfortable grip even when wearing gloves.
Metal-reinforced eyecups are tough and durable.
The hard-working chassis of the Viper is extremely lightweight, yet rugged, with the wonderful solid feel that comes when each and every part is machined just right ... and fit perfectly together. Even the eyecups are made to endure constant wear with a durable metal foundation. Tapered for a more natural fit to your eyes, these multi-position eyecups provide you with the most comfortable viewing around. You'll enjoy full field viewing even if you wear eyeglasses.
