Loaded with phenomenal design and advanced ergonomic features, FREEON™ has been engineered with a revolutionary aerospatial aluminum alloy (Kynetium™). This material combines Magnesium, Silicium and Titanium; the refined mixture of lightness (mg), strength (ti) and elasticity (si), designed to take extraordinary pressures and stresses. These technologies have been successfully merged into a stunning wraparound carbonium frame, incorporating fully adjustable Ergonose ll™ and Quick Change™ Interchangeable lens system. Soft and adjustable rubber temples increase Freeon‘s comfort finetuning and insure stability.
