Very thin. The white is see-through because it's so thin. But they're long underwear, not a fashion statement. One thin layer is just the right amount of extra insulation for being out and about in the snow, and they're thin enough to add additional layers (as suggested by another reviewer) for harsher conditions. Being so thin, they're very lightweight, but it remains to be seen how long they'll hold up to wear and washing. I have my doubts because, as I think I may have mentioned once or twice: they're very thin.

Have bought these for many years for my husband and they are great for all but the high-wind well below zero days. He's a medium but prefers the large for making sure the legs are long and he waist loose. This last order they got a big run in them at the first wearing; we returned them and STP sent a new pair.

At a fantastic price! These are a perfect weight for my husband to wear under his dress pants during cold months where it never seems to get warm enough in his office. It adds a layer of silky softness for comfort!

My husband is a postal worker and swears by these. He has to dress for the outdoors in the morning, but works indoors for an hour or so before heading out to do his route. Even if he breaks a sweat indoors, he stays dry and warm all day. I only wish they held up a bit longer, but they are silk....

These silk bottoms are so thin you can see through them, but they seem to be warmer than midweight poly. Their thinness makes them perfect for layering, either as the sole long underwear layer under pants, or paired with another base layer to double the warmth. I recently went skiing at Monarch, Colorado when it was 0º F (-18º C), with these as the bottom layer, nylon tights over them, and uninsulated nylon hiking pants as the outer layer, and was perfectly comfortable.
