Review on LAPASA Men's Fleece Lined Thermal Underwear Bottoms, Long Johns Light/Mid/Heavy Weight Pants 1&2 Packs (ThermoFlux M10/M56/M25) by Steven Notsinneh

I bought the heavyweights to try in Polar Vortex which hit Minnesota earlier this week. I walk a lot in the fresh air, so I wanted to find thermal underwear that would work in the cold. I've been wearing them under fleece-lined jeans (which I think are warmer than flannel pants) for the past two days. Yesterday (January 31, 2019) the morning air temperature was about -22 degrees Fahrenheit with a cold wind of about -37 degrees Fahrenheit. I could walk about 30 minutes. I was still a bit cold but they helped a lot. Today (02/01/19) the morning air temperature was about -4°F (with wind chill at about -14°F). They kept me much warmer; I could walk about 75 minutes and could have walked longer if my feet hadn't gotten cold. You passed my test; I am completely satisfied with Lapasa thermal underwear and will also recommend it to other family members.
