    • Great for Cold Winter Days
Team Name: Classic Size: Medium Color: Charcoal
These thermal underwear pants are very comfortable and do a great job containing body heat. However, I would not use them on mildly cold days as you will probably become hot. I live in a state where the winters get fairly cold, but I wouldn't use them for most of the winter days in the South unless I knew I would be outdoors for an extended period of time. It may be nice to have a pair just in case that occurs or you like spending time in the elements for a decent duration. ... show more

    • Great
Used these on a trip to New England and needed them on the coldest day. Very comfortable and warm under my pants. Better than buying insulated pants IMO.

    • Iceland vacation
Team Name: Classic Size: 4X-Large Color: Black
Got these for my husband and although he hasn't used them yet, I wanted to comment on the size. He is 6'3", weighs 205....using the measurements provided I got the 4XL and they are perfect. I was concerned they would be too big but measurements are very accurate. Fabric is soft, hugs his legs but not tight/constricting! Pleased with all of that, wanted to share it with others contemplating purchase, will update review once we return from our vacation. ... show more

    • Great Quality
Team Name: Classic Size: X-Large Color: Black
Husband really liked these for a bit of extra warmth this past winter. They fit under his jeans and were very comfy to wear. They wash up beautifully - no stretching out, no shrinkage - still look like new

    • Retain Heat Well
Team Name: Classic Size: X-Large Color: Grey
I bought this pair as an 'experiment' a 'test'. This pair passed my 'test' and exceeded my expectations. Not by much... but passed. My Primary Concern was how well they would fit, given the fact that we were trying to fit my odd body. With minor adjustments, they fit just fine... very comfortable. And so I went skiing. The thermal underwear did a great job of keeping my legs in a working temperature mode - not too cool, not too warm. I went on a hike with the pants delivering the same level of performance. I bought two more pairs of these thermal leggings. ... show more

    • Extremely comfortable.
Team Name: Classic Size: X-Large Color: Navy
I found the product to be very comfortable for all day wear. I have not tested in "Extreme cold" but they were perfect for days that started out at 32 degrees and improved to 50 degrees. In other words I didn't over heat at 50 and wasn't cold at 32. I don't think I'd wear them in below freezing weather for very long. ... show more
