Perfect - even better than my Houdini jacket

Everything it was advertised to be. I use this in fall as a wind breaker when running and one of a few layers in winter running. It’s very comparable to the Patagonia Houdini jacket except it’s got a few more really useful pockets. It is also stylish as heck.

I’m grateful for this jacket as it works on so many levels. I use it for running, early morning walks, and errands. I might grab a backup.

Awesome windbreaker

Perfect fit for running. Trim but not tight. Disappears when not needed. Super soft next to the skin. Love the back vents.
