Bought to wear under khaki flannel or fleece pants to attend fishing tournaments. I have long Landsend nylon underwear that actually keeps you warmer than these. When the sun comes out, they'll keep you warm with accented khakis. So my conclusion for them is: you let your body heat through, but the room would be very warm. I think in late spring and early fall you might want to use them (under a raincoat would be fine). What worries me the most is the email I received saying that if I gave positive feedback and sent a video or photo of them, they would send me a $30 gift card. Trust me they don't want a video of a 69 year old man wearing this! However, this means that most of their reviews are paid. Don't believe many good reviews. They're not bad, but they're not very warm and don't work as well as my usual Landsend nylon longies.
