Great fit, Not a Wind Sack
Admittedly my first run in the pants, but they were great. 10 deg C with gusts to 20kph and they felt great. I don't like pants when running as they will often get too hot and catch a lot of wind, but these were great. No restriction to movement and very breathable keeping my legs warm, but not overheating. And they shield from the wind, but don't act like a parachute.
I can be pretty easily talked out of a run, so if the weather is too cold, I will bail. However, these pants are going to take away a lot of excuses over the next few months, which is what I was hoping for.
