One of the popular mountaineering/trekking stores in Vienna, It can be hard to find people on…read moreweekends still, most are friendly and helpful if you get them except for one guy who is quite gruff (I just avoid him). On the plus side, I think they are more knowledgeable than the generalist sports stores. The prices are not overly competitive but that is more typical of Vienna, and they have stock items once in a while.
