PRODUCT OVERVIEW
SportRx Frame Width™ (SFW) is the measurement our Sports Opticians use to find the most accurate fit possible. Unlike most eyewear measurements that have little to do with fit, SFW serves as an indicator for how well a frame or goggle will fit your face.

SportRx Frame WidthTM (SFW) is the measurement our Sports Opticians use to find the most accurate fit possible. Unlike most eyewear measurements that have little to do with fit, SFW serves as an indicator for how well a frame or goggle will fit your face.
DETERMINING YOUR SFW
Use Eyeglasses and Not SunglassesUsing flatter eyeglasses makes for a more accurate measurement. It takes a bit more finesse with wrapped sunglasses to get an accurate SFW measurement.
Make sure the glasses fit!Since we're using your glasses as a template for ideal fit, make sure they're a pair that are comfortable: not too wide, not too narrow. A quick glance in the mirror will show if the frames spread too far past the edges of your face or seem to 'pinch' it.
Have more than one pair?It never hurts to have more than one 'frame' of reference! If you have more than one pair that you love, you can measure multiple pairs and get an average.
How/What do I measure?Measure with the temples opened out fully. Aim for right behind the hinge and measure from the inside of the frame material of one side to the inside of the other side.

Rubber nose pads keep your frames in place and optically aligned even as you sweat, jump, slide, bounce, you name it.
Rubber temples aid a secure and steady grip so your sunglasses can rest comfortably on your head.
Unique frame design allows for increased airflow which wicks away and drains any sweat or moisture you work up.
Strap integration ensures that the frame is securely and comfortably placed around your face allowing for peak performance.
There’s nothing worse than lenses that fog up – so ditch blurry vision with an anti-fog coating and experience a world of clarity.
