I wasn't sure which of the women's wool long underwear bottoms would be the best, so I ordered the Icebreaker, the Marmot, and the Smart Wool. The Icebreaker long underwear bottoms are 1) just a tiny bit scratchy 2) much too tight in the elastic waist band, which was both unflattering and uncomfortable and 3) too high up on my torso, with the waist coming far over my belly button. The Marmot have kind of thick seams in the legs that makes them less attractive and less suitable for use as leggings that might show (versus long underwear that would never show), and they were also baggy in the butt and high-waisted. In contrast, the Smartwool have a much softer knit, and they have a nice, covered elastic waist band that hits just below my natural waist without binding or creating a muffin top (and I am thin, so the Icebreaker ones had to be really tight in the waist to make that happen). I LOVE the Smart Wool bottoms, though I do also love my Icebreaker wool tops.
