Frame: Black Plaid
Lens: G30 Polarised/VR50

I love these glasses, they fit my face perfectly, lots of protection against flying stuff (my juliets left a bit of a gap between the frame and my cheek, and i was always wary about using them as safety glasses)

im not a huge fan of the G30 polarised, it has a orangey pink tint to it, and messes with my colour perception (im a photographer) - when they are available i will get a set of Black Iridium Polarised lenses to use when im out photographing.
when im not out photographing they are a great lens, the contrast boost is great, and they seem to let a little bit more light through, which is handy as it starts to get dark
I do love the Black Plaid Colourway

i havent really used the VR50 lenses, as i understand it they are better suited for overcast weather, its the middle of summer over here

the Switchlock system works very smoothly, changing lenses takes 30 seconds or so.

my new Go-To glasses, i still wear the Juliets (black iridium) when i need colour accuracy, but the fast jackets seem to grip my head perfectly, fit like a dream, and the polarised lenses are awesome (even if it messes with my colour perception)

Frame: Polished white
Lens:
oo red iridium polarized/g 40

I love these! Actually I would say they are the best sport sunglasses I ever had. Lens choice is perfect for any condition and sport. I do a lot of mtb and road bike and both lenses shade are perect in a wide range of light condition. Only thing I don't like is that you have to clse the stems to make the switchlock work.

Frame:Fast Jacket
Lens: Black Iridium Polarized

This is a great frame for anyone that cannot fit into a flack or Half Jacket. The XL lens is perfect if you have a high nose bridge and or low cheek bones. Purely a sporty pair that I like to wear when I play golf, or throw in the other lenses for shooting range. Love them!

Returned the Fast jackets because somehow they made me feel dizzy. G30s more so than VR50. I gave it a fair try for a few days; went on mtb ride with VR50. Going downhill on pavement at high speed felt a bit weird. However VR50 lens tint is excellent for riding on trails. In spite of big lens coverage wind protection wasn't that good for me. Some air turbulence got in from the sides. Styling on the other hand is excellent. Fit is good and secure. Fast jackets are stiffer and bulkier comparing to Commits or XXs.

Frame: Lemon Peel
Lens: Fire Iridium / Persimmon

Purchased these at the Chicago O'Hare Airport O- Store. This was the last pair they had and the lens was damaged.

I was surpised at the frame. The yellow seems to be a thick coat of paint rather than actually Yellow O-Matter. The switchlock technology is very cool, but does take some getting used to. It's not very easy to activate and your palm/hand prints still get all over the lens.

The XL lenses which are larger offer great coverage and the high cutouts are good for asian faces or folks with high cheekbones. The frame shape is a little odd, taking cues from both the Flak Jacket and the Half Jacket. The frame looks wide on many people, including myself because the angles of the ear stems (like the Half Jacket). If those angles weren't there, the glasses would look much better. Icon placement is not good, as well. Hiding the icon on the tops of the glasses does not "Advertise" well.

Frame: Polished Black
Lens: Blk iridium/persimmon

I've been waiting for this pair. I've always liked Half Jackets but found them small even with xlj. I like the fit of Flaks but found the frame a little boring. This is the best of both. Great lens coverage, super comfortable and they sit nice and square. The change out is easy using the switch lock. Black iridium is not my favorite so I opted non polarized and I'll upgrade later. The Persimmon will come in handy for indoor shooting. I'm stoked about these.

The Fast Jacket will seemingly be available only at O-Stores until production levels catch up and are able to supply other accounts purportedly sometime in July...
While the overall shape most closely resembles a Flak Jacket, fit certainly differs. The frame fits a bit wider through the temple, more similar to the Radar. The cored-out portions of the arms give the frame a softer, more comfortable flex. It "feels" like there is much less frame (like an M-Frame) until you look in a mirror. Angles on the arms are fairly aggressive, giving the frame a more purpose-built look. This is a stark contrast to the more casual style of a Flak Jacket.
Lens cuts are larger. The Standard cut is more similar in size to a Bottlecap lens, possibly even an Icepick. The XL cut is significantly larger, wrapping further back on the cheek towards the ear as well. Coverage with the XL feels a bit more like a Radar Range, just in a 2 parts as opposed to the shield.
I'm a fan of the Unobtainium earsock too, which takes on a little of the Scalpel earsock shape.
The Switchlock lever/pin mechanism works very smoothly, and most people will find it simple. I have never had trouble changing lenses in a Flak Jacket, so have found the new system rather unnecessary. I suppose some will like it, and some won't.
Aesthetically, I really like the Fandango-style icon application! As a whole, the frame boasts a purely sport-function, purposeful style. You will not see as many suits walking around in this frame as you do with the Flak, if any at all! It is another sport innovation that will do an excellent job for what it was designed to do, but I am guessing there will be much less crossover to casual wearers like the Flak and Split Jackets have had.
