Started to wear this one on some cold days where I would be out all the time.
I was out yesterday for 2 hours, with some walking and some standing still, and it was about 0-2 C°.
Off course if you don't move you'll eventually get cold at your legs at those temperatures, but while walking, there was a noticeable difference with the 14oz indigo I had been wearing for 3 months straight now. Until let's say 8 C°, the14oz and its admittedly tight weaving does a great job.
But for colder you need the heavy weight 




Since I was in a public place (I don't own a dryer) I let you imagine how I did look...
