When climbing anything, whether steep crags, ice, or trees, you will need eye protection. Stones, dust, ice, twigs and leaves can get into your eyes which could impair your vision. Certainly, when your life is literally hanging on a thread, you will want to have full command of all your senses.
The Bangerz HS 2000 Wraparound Eyeguard does a great job of protecting your eyes not only from foreign materials but also from your own sweat. Its wraparound design guarantees complete frontal protection ensuring that nothing can get through to your eyes while at the same time maintaining your peripheral view. To keep your brow ridges from sweating profusely, vents are incorporated into the sides of the frame to allow air flow. This eliminates, or at least minimizes, the likelihood of sweat getting into your eyes. It also helps in keeping the lenses from fogging.
The HS 2000 uses a one-piece polycarbonate lens. This is a shatter-proof lens that is capable of absorbing high impacts. It is coated with an anti-scratch and anti-fog veneer. The nose is made of soft-molded rubber making it comfortable to wear. In the event of an impact, it is capable of absorbing a good amount of the force. It is also hypo-allergenic thus there is no need to worry about unwanted rashes on your nose.
Instead of temple arms, the HS 2000 uses a washable head strap. When properly adjusted, the strap can do a better job of holding the glasses in place even when you are repeatedly jolted as often happens during a climb.
