When hunting in the high alpine regions for sheep and goats weight can become a real headache. From the weight of your tent, to your boots, to your rifle, every ounce has to be hauled up and down those steep slopes. In the optics department your spotting scope is a must, but quick access is not possible with a high powered spotter. That is where the Vortex Viper 8×28 binos step in- feather light and small enough to fit in a chest pocket these sharp binos can be easily accessed at any time to check on that white blob on the mountain. Tough enough for mountain hunting and backed by the best warranty in optics there is no excuse for not having these binoculars.
