Dear
honhon! The Rocabar is the older model. So, if you would want this, you might need to be quick...

The Alamo is new and according to my SA would still be available for a while. I tried both and thought that the Alamo is a bit lighter and softer although it is the same material and the same size.
You probably feel that the Alamo looks bigger because the stripes of the Rocabar give a bit more structure to the lady underneath. This is why I decided on the Rocabar as my first poncho - but now I need the Alamo as well!!

It is more elegant and definitely worth a try!
