I ordered these pants to compliment the Calor jacket that I picked up earlier. I was tired of having to wear a ridiculous amount of layers to stay warm in the treestand during mid to late season whitetail hunts in Missouri. I wanted an ensemble that was warm, but not bulky. The Calor fits the bill. With minimal base layers underneath, I can sit all day and never get cold. I liked the leg zippers that went from cuff to knee to allow ventilation when you are walking to and from the treestand to prevent sweating. If you want something warm and light weight, you can't go wrong with the Calor pants and jacket from Badlands.
