I am going to go to my LBS tomorrow and see if they carry the Topeak.

Also, does anyone know of any sunglasses you can slip over your regular glasses that are a wrap around style (meaning they have sun protection on the sides are well). Unfortunately I am blind as a bat and need to wear my regular glasses to see (can't do the contacts thing) and I have a pair of clip ons but I need something that shields the sun on the sides as well. This question is probably a long shot but I thought if anyone would know, the folks in here would.
