Depends what it is.
The whole "it was amazing" thing is actually kind of revisionist history. Technically, the product was pretty crappy. It was more or less all 5000mm/5000g, never over 10k IIRC, so soaked by end of day, easy enough to tear, disposable stuff. There wasn't any feel of quality. I say this as someone who has owned (and I think I still own a couple of hoodies) a bunch of Siver. Some of the stuff looked good, and it cost next to nothing compared to the alternatives (especially on discount), but that's as far as it went.
I think if they were to bring it back, yes, the brand would still mean something. And I even think it would make sense, in order to create some brand separation between the more mainstream, "for everyone including families and weekend warriors" Orage brand and a more freeski-specific Siver Cartel. But they'd have to actually produce a top-quality product.
