Great all-around base

  • Familiarity: I've used it several times
  • Fit: True to size

These are a great weight for day to day use. They provide enough extra insulation to keep me warm down to about 20 F when I'm walking to/around school, or just around town, but they're thin enough that I'm still comfortable in them once I'm inside. They're my favorite base layer/long underwear that I own because I can wear them literally all day without getting too warm or cold. I love them so much, when I take my pants off at home, I usually keep these on for the rest of the night.

Good for getting around

  • Gender: Male
  • Familiarity: I've put it through the wringer

I'm a big fan of these, but I use them primarily for walking around town during the winter ( about 20 degrees Fahrenheit). They are really well put together and feel amazing to wear compared to synthetic long underwear I've used. I have a size small and typically wear Levi's 30x30 in jeans and they fit me pretty well.

keeps me toasty

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

I just received a pair of these bottoms and had a chance to test them on a 3 mile snow hike in single digit temps in a foot of powder.

I wore them as a base layer under my (insulated) Spider Troublemaker pants. I stayed perfectly warm the entire time without issue. I do wish the bottoms had more elastic in the ankle as I felt that they may ride up my foot over time.

I'm stick thin. If I had any meat on my bones to speak of, it would be "skin tight", but mine have a big of "room" to them due to my size. If you're average, they will fit as intended. Waist sizing (I wear a 30) is accurate.
