Lots of options out there; look at the Memphis Shades line, they have a great product with excellent customer service (not only initial sales, but folllow-up service if necessary as well). Some that come to mind that are slimmer and sportier are the Pop Top and Alley Cat shields. Just make sure you at least consider the correct height (they have measurement guidelines on their website based on your height/sitting position) or go buy a local bike shop and use one of their "measuring shields." Sometimes if you get the wrong height, it can create a lot of head buffeting at higher speeds for people.
