M50 breathability vs. commercial windshirt nylon on 03/02/2011 17:13:54 MST Print View

I know not many of us have had a chance yet to test Thru-hiker's M50. This question is for anyone who has (or anyone who has seen breathability numbers). I need a new windshirt, and I'm weighing making one out of M50 against buying a Montbell Tachyon, Patagonia Houdini, Camp Magic, etc. Any ideas about how I could expect the breathability of the M50 windshirt to compare to these others? Thanks.
