The purpose of the outer shell of a Parka is to lightly and durably contain the insulating material and offer some wind resistance.

I'm not sure on the weight of the resulting fabric, but if its in the realm of existing nylon shells and offers greater durability, its a massive win.

ah - so it's possible that the reasoning behind this is the low weight mixed with its huge strength/durability gains?

In theory - although its just conjecture. There are so spec's out there on the Jacket Weight or its windbreaking properties.

If its as heavy as Canvas, then its just novel.
