I lost the fit over sunglasses I bought locally (in Israel, where only one model is available). I was very happy to find a variety of styles and sizes, especially a nice feminine style.

These cover my glasses well and block out the sun well. Even though I have a smallish head and I measure my glasses before ordering, the size small is a tad too small, in that the tug at my ears a bit.

Overall, well worth the price.
