Swiss Army Duffle bags ques.
 

On weekends one sees lots of Swiss men with official Swiss Army duffle bags, I noticed that these duffle bags have the German, French and Italian equivalents of "Swiss Army" but also in ENGLISH "Swiss Army"--but NOT in ROMANSCH (the 4th official language of Switzerland)...why would the ENGLISH "Swiss Army" be used?

You can see here the official equipment of the Swiss army, and the duffle bag has 5 inscriptions including "Armada Svizra".

It would be interesting to see what bag you are referring to, maybe it's some sort of fashion brand which is not official equipment?

Romansch is actually not a full official language. It does not have the same status as German, French or Italian.

Well, yes and no. Article 4 of the Swiss constitution states while Articcle 70 states

I saw lots of these duffle bags, they all had German, French, Italian and English, no Romansch. But back to my original quest. why English at all?

Because English is the de facto lingua franca of Europe?

Official (in the real sense of the word) Swiss Army equipment is not marketed anywhere, at least not officially (again, in the real sense of the word). For example, a real Swiss Army knife looks different from what people think a real Swiss Army knife looks like.

Probably for the same reason that Swiss trains around Zurich have German and English announcements (sometimes additionally French), and around Geneva have French and English (sometimes German), but I have yet to hear Italian announcements on a Swiss train as I have not been to Ticino.

In the Italian area they DO make announcements in Italian (and sometimes English and/or German).
On trains in the Graubeden area in Romansch and English and/or German--occasionally English only.:)
Switz. is very tourist oriented, so using "other" languages are based on the "audience" they are dealing with. In Zermat there are lots of signs in Japanese--I've arrived in Zermat and the station plaza was wall to wall Japanese (tour groups).
