I would feel that it would, too. Having said that, I’m not sure it matters; in fact, the last jacket I bought (OR Transcendant Hoody) had the narrow baffles. I notice that the 2019 version of that jacket has baffles that are about twice as wide.

So why don’t I think the wind proof-ness of the down garment matters? Because, if it’s windy, I layer my Pertex rain jacket over it as a windbreaker - eliminating any potential problems with the insulated jacket.
