As evidenced by the dead link on my previous trizip musings, Boreas once again discontinued their trizip offering.
When asked at a trade show the response from a Boreas employee was that it was removed from the line because the Boreas designer and Dana Gleason are "good friends."
What I read into it is that MR didn't mind so long as their focus was on military and hunting sales, but now that MR has switched focus back to a recreational pack line the Boreas was much more of a direct competitor.
If this is in fact what happened this could be a comforting case of mutual respect and accommodation that is often all too lacking in the outdoor gear industry.
But on the other hand, it appears to still be for sale in Germany:
