Their Weizen glass sports the brewery label plus the inscription "Weizen".
In the southern part of the German-speaking regions glasses like this are called "Frischestangerl". They have befome fashionable within the last few years for the purposes I listed above. I don't recall them being in any way traditional (although there are medieval glasses with similar shape, the use of those seems to have been discontinued for several decades, if not centuries).
So, as stated above, it can be used as an all-purpose lager glass.
