So, for the production versions available this season, Neither the XT3 140 nor the XT3 130 use Grilamid — both of them feature Lange’s “dual-core” Polyurethane lower shell and a Polypropylene upper cuff.

Just talked to Lange’s NA Marketing Director and he re-confirmed that the 140 does not use Grilamid. While I obviously don’t have a way to test that, I trust him, and I suspect the update just hasn’t been effectively communicated throughout the brand.
