Save big and save now on what many consider to be the ultimate sports eyewear. As you would expect, we have these in limited quantities, so get a pair of M2 Frames while you can.

We can trace the lineage of the M2 back to the mid-eighties. It all began with the Blade and RazorBlade sport glasses. These lead the way for the release of the Mumbo in 1989 and then various incarnations of the M Frames of the nineties. M Frames have been field proven by just about every legend to pedal a bike, which means these winners are guaranteed to allow you to perform at your best. The M2 is the latest version which features the same great design with a more reliable frame construction and contemporary Oakley lens technology.

Many cyclists prefer to use a single lens sport glass (also known as spherical shielding) when selecting eyewear. They are lightweight, easy to clean and they are void of that pesky nose bridge that interrupts your vision. The lightweight O Matter frames are super durable due to Oakley's polycarbonate construction. They have a happy balance of flexibility and rigidity, which leads to comfort and structure for lens support. Like all Oakley sports eyewear, the M2 feature the Three Point Fit system. This means just the arms and nose bridge will come into contact with your head. These contact points have Oakley's Unobtanium grippy material which provides an ultra non-slip grip. The single pin hinge is solid and offers smooth action when opening and closing the arms.

Perhaps the most noteworthy feature of the M2 is the lens, or should we say lens clarity. Developing a one piece shield-style lens without distortion is no easy task. With the M2, Oakley breaks out Polaric Ellipsoid technology for the ultimate in visual clarity through spherical shielding. We'll explain. Polaric Ellipsoid is actually geometry and measurements that span the lens shield with accurate equalization between each point along the arc of a lens. The lens is mapped and plotted across its arc to produce a non-distortive vision at all angles of vision. Beyond perfect vision the lenses feature Plutonite UV protection and Hydrophobic for water repellency and smudge protection. The classic Iridium treatment provides glare reduction and a tuned light transmission in brighter conditions.
