    Crazy comfort before, during, and after you work out.

    The SmartWool Women's Microweight Bottom takes care of you from the moment you put it on until you take it off. Flatlock seams and an elastic waistband are comfortable as soon as you slide into the Microweight Bottom. Super-soft merino wool wicks moisture and breathes well to keep you dry and comfortable for your entire workout. You won't have to go slinking home right after your workout, either, thanks to merino's odor-fighting properties.

    Never can have too many baselayers

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Small

    Good buy!
    -super soft
    -love the waist band, its not too tight to show my love handles
    -the length is not too long like normally on other baselayers but there is still a little bit of extra material that bunches up at the bottom, I would recommend getting 3/4 length for skiing!
    -they seem kinda thin but def warm since they are wool
    -mine have not smelled yet and I have worn them a few days in a row :)
    - I also have the stoic baselayer ones and like the back of these a little better because there is no seam on the back butt.
    -they are cute just to wear under a dress too, stylish
    -it says the recommended use is running, I haven't actually ran in them yet. I use them for snowboarding under my ski pants.

    Buy Them!

    Fit well (not too tight)

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: small

    The material was very comfortable, was not scratchy at all. The pants were very thin and almost see through but that is expected of a base layer. I wore this along with another pair of leggings and skii pants to Alaska in the winter (-40C/F temperature) and my legs did not feel cold at all.

    Great to get on sale!

    I love smartwool and try to wait for a sale to buy it. It doesn't itch and you can actually wash it in the washing machine and it won't shrink. It doesn't smell bad like polypropylene, either. I wear it as a base layer for kayaking.

    Love the flat waistband

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

    The new flat waistband is amazing. I always hate long underwear because they dig into my waist but these fit great at the waist and are flat against my skin, not digging in at all.

    Perfect for hiking

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

    I'm in the PNW and wear these all the time. Got totally stuck in a deluge yesterday and although my rain pants weren't up to the task, because I had these wool tights on, I was still just fine temperature wise. Only thing that keeps it from 5 stars is that they sag just a bit in the crotch.

    The best!

    Bought these as an added layer for a trip to Patagonia, Chile and all I can say are these are the bomb! I ended up wearing just these with gaitors and my boots, keeping rain gear in my pack in case of bad weather, and these tights made the best, most comfortable hiking pant imaginable. I actually developed a rash on my inner thighs from hiking in wet rain forest conditions (wearing traditional rain-resistant, convertible hiking pants from Prana), and these tights ended up being the only thing I could wear for a week that didn't chaff or irritate. I was worried they would be a little see-through, but they weren't and they worked great for hot days AND for cold. I had a couple falls that ended up tearing a hole or two in the cloth, but i sewed them up happily, as these are now my go-to's for any outdoor activity!

    love them

    I use them for xc skiing, road cycling and running. These light weight bottoms are really warm and so thin so it doesn't feel like I am wearing two layers. I liked them so much I got my mother a pair that she wears under her every day pants and she has not stopped talking about them yet!!

    best merino legging!

      They're become my go to underlayer for winter. I wear them under to work. I wear them as my base layer when skiing/hiking. I've even worn them to bed! These bottoms are amazingly comfy, never itchy. It will keep you warm but not too hot. What more could you want?!
