Another old design being upgraded - leather oculars were lowered for better fit, domed nuts were changed to sunk flathead bolts, strap attachment was also upgraded. Performed in brown leather and polished brass.
Well, they are designed as real life protective goggles, so they was build to withstand more than non intentional beating. This particular design of the frames (solid frames) will also withstand some serious beating and may not be broken even if you deliberately try to do so. The other design, however, one with th lighter frames, is not that hardcore, but still as reliable as you regular protective goggles. After all, it is all, it's all made of reliable materials, so to speak. Thick leather, brass, bolts and nuts, lenses made of 3mm perspex. What could happen uless you hit these goggles with a hammer?
