ThermajohnMen's Ultra Soft Thermal Underwear Long Johns Set with Fleece Lined

I've got about 4 pairs of thermals. These are the best. Took them to Iceland in November. They do the job. Warm, comfortable and good fit

They look and feel nice but I wore mine in the arctic circle and at some points indoors managed to sweat through the armpit area and ruined two t-shirts that were work on top as the black fabric was NOT colourfast.
