I'm mostly a sunglasses guy but I was rocking the Fall Line for most of last season and I have to say, I'm pretty impressed. The Prizm lenses (I had Black Iridium and Rose) did the job in the vast majority of conditions. I have pretty sensitive eyes (I wear sunglasses pretty much every day) but even the low light rose lens kept me comfortable on all but the brightest of days and the clarity was second to none. And even the Black Iridium, their darkest lens I believe, was manageable in low light conditions, if not ideal. There are fancier technologies on the market with lenses that change colour at the touch of a button, but I like really like the simplicity of the Oakleys and wouldn't want to add weight when these did everything I wanted of them already.
The medium fit of the regular Fall Line was great for me, but Oakley now also offer an XL and XM version to fit all face shapes. The regular goggle offers a decent field of view, though the thick foam which makes these exceedingly comfortable, does reduce this slightly at the extremes. - Twig
In skiing and snowboarding, taking the Fall Line refers to the line down a mountain which is most directly downhill. Inspired by Line Miner and fusing the large field of view from a rimless goggle, Fall Line is an addition to Oakley's “LINE SERIES” of cylindrical style snow goggles. With a medium-sized fit , Fall Line is optimized for a wide variety of faces and is engineered to fit perfectly with most helmets. Designed with Oakley's Ridgelock Technology, changing lenses is quick and easy while still allowing for a complete lens seal to prevent harsh conditions from penetrating into your goggle. Discreet frame notches at
temples provide compatibility with most prescription eyewear.
