I have measured the Frazier CFM, air permeability, of a very large number of windshirts. Every one of them has vocal proponents on this forum. The air permeability measurements ranged from a low of .33 (Dri Ducks) to a high of 100.59 (Acteryx Squamish). The Patagonia Houdini is not abnormally high at 38.12; it falls approximately 1/3 up from the bottom of the spectrum.
The above is science; the following is a subjective judgment. For use in environments where your MET level varies widely but, averages approximately 7 (UL Backpacking), the Houdini provides a near optimal wind shirt solution.
Regarding abrasion resistance, the amide group -(-CO-NH-)- provides hydrogen bonding between polyamide chains. This gives nylon high strength at elevated temperatures; toughness at low temperatures; combined with its other properties, such as stiffness, wear and abrasion resistance, low friction coefficient and good chemical resistance. These properties have made nylons the strongest of all man-made fibers in common use.
Polyester is the other common windshirt material, but for the same windshirt weight, it will not handle abrasion as well.
