I have the Redkettle wind shell I'll be testing in west TX desert end of January. Will be lows 30--40 with a ton of hiking, eager to see how it performs with different base and mid layer combos. While researching ventile more, I did come across
Hilltrek (nearly all Ventile) and Keela (
smock,
jacket), which I've saved for future testing. Single layer ventile options from Hilltrek would probably be the closest to breathability of the Redkettle windshell, but you have more options on style/features (e.g. hood). The "hybrid" cool too, dual layer on hood and shoulders, single layer elsewhere. The "Cotton Analogy" uses Ventile on exterior and Nikwax's Analogy liner to wick moisture away. All pretty darn expensive, then include shipment to USA and it's tough to stomach. But I'm a sucker for these smaller companies and ventile in general.
