graham0810wrote a review of Oakley XS Five Sunglasses on June 2, 2008
I am a small adult female and these are the perfect size for me! They don't take up a ton of room to store in a bag or purse; they don't fall off or take up my whole face, but they are still full enough to look good and provide adequate coverage.
As a word of caution, in terms of the size, these really do appear to be kid-size glasses to me. They would be far too small for most people older than 11 or 12--that is, unless you have a really small face. They look ridiculous and/or just don't fit on several other adults who have tried them.
