The TOV does not appear to have baffles at all. In the photos I have seen it looks to be, like many other down outer garments, of sewn-through construction. If that is the case then the pattern used for the sewing through is pretty much irrelevant when it comes to warmth; the pattern is more of a fashion issue. The weight of the extra thread used to create the pattern would be negligible.

Baffles are strips of lightweight fabric that are sewn to the outer and inner layers to form tubes that are then filled with down. The baffles define the thickness of the insulation by separating the inner and outer fabric layers. With sewn through construction, the outer and inner fabric are sewn together at intervals; there is no significant insulation where the layers are sewn together.

The "diamond baffles" to which you refer are a cosmetic feature and have nothing to do with function.
