    I own several “thermal leggings/pants/base layers” from all across the spectrum, $10-$110. My previous daily legging was the $50/$60 2.0 Under Armour from Scheels. I have thermals from Younkers (32F brand) and base/long Johns from Walmart.

    This winter (2017-2018) has been historically cold for my region. -15F was common on most days. I found myself wearing 2/3/4 thermals/base layers to keep my legs warm underneath my khakis/slacks at work.

    My hope was that these $100 Merino wool leggings would solve my problem. I was wrong. I don’t understand the marketing behind this product/brand, when I had to pair these leggings with another baselayer to stay warm.

    I was disappointed in the overall warmth of the product. The quality is evident. The lack of odors after extended use is a nice touch. However, the overall performance of the product was comparable to the $50-$60 UA bade later I purchased from scheels.

    Save your money. My recommendation for best value would be the Walmart $20 Long Johns. Best overall value in terms of warmth/cost ratio.

    Warm. Really nice quality

    Very warm yet wicks away sweat. Great for winter storm days

    They fit well and they are warm!

    Wow ! Just received a REEBOK Poly Base layer instead of Wool Leggings
    Waste of time

    I requested these leggings for my husband knowing that he is very active outside during the winter time and his always looking for a good base layer of underclothing. Although he is tall, athletic and normally wears large sizes, I ordered the medium size leggings for him. This was good, he told me because the leggings remained snug while he wore them and the snugness added to the warmth of the fitting. The fabric was soft and did not irritate or chafe him which allowed him to remain comfortable while wearing the leggings. I recommend these leggings as a good base layer during outside activities in cold weather, however, for a good fit, I recommend getting the next smallest size.

    Very fine Merino wool and because it's real wool, it's really warm. I thought they had some stretchy material in them, but no, %100 wool. They are thin and flex and so far, cling pretty well, although you don't want to dry them in the dryer, that will probably make them shrink badly. Very nice, I think they will be my go to winter wear under levis too.

    These are the nicest long underwear I've come across. The wool is so soft, very tightly woven, and they fit like a second skin. Breathable and moisture wicking. High quality stitching. These are like the Cadillac of thermal underwear. The only thing that would make them better is if they were made in America, but the tag says they're made in China.

    - 100% Merino wool
    - Provides significant warmth but not during real cold weather
    - Regulate temperature; never sweat in these

    - Expensive :(

    Great for warmth & wear. Be nice to have more coulour varity. Great product...
