The EG2.5 is a brand new frame from Electric this year that has a similar shape to their classic EG2 frame, but it's a bit shorter with more of a square shape as opposed to the roundness of the the EG2.
The frame and strap holds up like a semi-truck in a car accident with a smart car, and I've found that the reflective lenses from Electric fare well in all conditions, rain or shine, bluebird or fog. Plus they're great for checking out chicks in tight ski pants without them being able to bust you.
I'm rocking the purple and black frame...because I don't like to go skiing with something on me that's not purple.
I've been wearing the EG2 for the past three years and love the staggering amount of peripheral vision that comes with it (check out my review here: http://www.newschoolers.com/ns/content/reviews/action/read/id/1596/), but I jumped at the chance to try out this new frame to mix things up a bit...and I wasn't disappointed. You still get the lengthy side-to-side vision of the EG2, but with a little less height, which is great for all the people out there who don't have as big of a face as I do and who may be intimidated by the girth of the EG2.
I've got a chrome lens on mine, which means that any scratches are a bit more noticeable on the outside, but I've yet to experience any vision problems from the inside, which once again proves that Electric makes some of the finest lenses in the game.
