      2 Pack Heatgen™ Long Johns is rated 4.3 out of 5 by 15.
      Rated 4 out of 5 by from Ready for Siberia Bought for my son who will travel to Siberia during the winter months. Pants feel soft to the touch and quite light, yet warm, hopefully the right sort of pants for the purpose.

      Rated 4 out of 5 by from Thermal underwear for my grandson My grandson stated that he was going to purchase thermal underwear so I felt that Marks & Spencer would be the perfect place to buy. I purchased this pack of Long Johns for him and he seems very pleased. He said they fitted and that they were warm. As long as he is happy then I am happy.
