I got a pair of Wrangler jeans lined with Thinsulate for Christmas. They are awesome. Warmest pants i ever had. Its like wearing coverall pants. Ive been wearing them outside during these past 2 blizzards while clearing snow on the tractor. Figured this would be the ultimate test since the wind was blowing so hard. They past in my book with flying colors. Legs never got cold. You can get them in regular Blue or Brown. They came from Sportsmans Guide. They have some lined with flannel, but I figured the Thinsulate would be much warmer. My dad got the flannel ones. I need to ask him how theyve done. I highly recommend.
