We’re not huge fans of wind shirts that aren’t breathable. That’s why we think the Patagonia Houdini Air Jacket is such a versatile jacket. When it’s not raining, a wind shirt provides just enough protection from wind and cold without having to wear a waterproof rain jacket that makes you feel like you’re in a sauna. The Houdini Air uses a fabric that is much more air permeable than most wind shirt fabrics, which means you can wear it across a wider range of temperatures and exertion levels.
