Maybe Leibwächter (first result of a quick search)?
Having tactical gear in mind I feel UF-Pro is hyped and overpriced. I like Helikon-Tex (Poland), Clawgear (Austria) and Arktis (UK) a lot. Especially the later two have similar pants in good quality.
Not exactly my favourite style, but thanks for the tip. 😅
Engelbert Strauss, the Gucci of working cloths :p
(I say that while owing jackets a pair of pants and a t-shirt by them gifted to me as a teen by my carpender dad)
Try Cerva, I think it is Czech or Slovak.
I don't know anything about the owners of Engelbert Strauss, but the article only says that they don't like wind turbines (at least at one place). Do they also support the AFD, hate LGBTQ, and dismantle government organisations? If not, they are certainly a lot better than Musk, not similar.
