Definitely great sunglasses. I also own the Twitch's and was looking for something a little bigger to block out a little more sun. These definitely do that, and are probably the most comfortable glasses I have ever worn (definitely more so than the twitch's). As for size, these are definitely not as big as some people make them out to be, I have a very medium head size and these fit perfect (but as for any sunglass you should try them on first). Overall, Great shades, buy em!
