Used this jacket while snowshoeing in -10°c weather and took it off after about 5 minutes. It is incredibly warm. Put it back on while we had stopped by a lake with winds at about 20km/h and didn't notice it at all. For the most part I wore a shell over top of it but when it was exposed to the snow it was very water repellant. A great piece of gear for anyone that wants to do winter adventures.
