Tired of buying long undies that feel like fiberglass insulation? Look no further. Always wore St. John's Bay thermals from JCP till they stopped making 'em. After wasting money on Duofolds etc....I just recently found the "Holy Grail of Long Underwear" right at my local Sears. These are 100% pure cotton with flatsewn inseams and they are absolutely the best I've ever worn. (I'll admit that I have fairly sensitive skin for a Maine construction worker...But what can I say?) I'll wear my "fiberglass" thermals over my Covington's on those below zero days. Covingtons rock!!!
