In reply to Fredt: Yeah, there's a few issues here.
1) With Neoshell now out and Gore Pro and Active Shell out, it is no longer that new.
2) As ice.solo says, DryQ Elite and others are just rebranded eVent.
3) There may be concerns over its long-term durability.
4) All the economics of supply/demand.
The biggest change will come when Gore release their new fabrics in the next year or so as they are - oversimplification - changing the way their membranes are constructed.
