The O Frame 2.0 Pro XM OO7113-01 Matte Black Fire Iridium & Persimmon is an updated version of the hugely popular original O Frame with injection molded high impact lens protection and better optics on this entry-level ski goggle. Notches at the temples allow prescription eyewear to still be worn and larger lenses with streamlined frames give great peripheral views. This is the XM version frame for a medium-sized fit. There is also a second lens included to give protection in any light condition.
