Great extra layer for frigid days...
This is a great pair of slim fitting fleece pants to be worn as an extra layer on frigid days.
The sizing chart is perfect. Do not oversize.
These should be worn over your normal base layer and under your outer layer. It is meant to add insulation to your outer layer but not to replace your normal base layer or its properties.
I use them everytime the temp is less than 20*F. Worked great in 0*F with wind chills into the -10*F.
