My wife digs them. She has Black and Blue. And if you are into Volleyball Kerri Walsh is a fan of them as well. They have good coverage. Little on the large size, but that is what she likes.
Yes,they will be most used for the beach,and little bit for casual use.
I would say it's almost the same size as the Antix with thinner stems.
You sure,to me they seems little bigger,thats why Im asking for a pic,it would be of great help.
