    • Far exceeded my expectations for the price I paid for the set
Size: XX-Large Color: Black
So comfy and warm! Great fit and really nice feel to the fabric and fleece lining, smooth but strong. Easily fits underneath my other clothes when layering for winter weather. Also noticed after several washes color is not fading. I am beyond satisfied with this purchase. Buying more soon in different colors. ... show more

    • So comfortable and so warm!
Size: Medium Color: Black
This set exceeded my expectations. It is soft and silky material that fits like a second skin and is so comfortable. Yet it is surprising warm just as needed. Perfect! I am so pleased.

    • Comfy and warm
Size: Medium Color: Purple
American Trends Women's base layer is comy, warm, and easily fits under jeans and other clothing. It kept me warm and comfortable all day long. It wasn't binding and allowed me to move free. It is very light weight. I did some yard work while wearing it and it kept me warm but I could easily move. The color is luscious. I ordered more sets. Highly recommend ... show more

    • My Second Skin!
Size: XX-Large Color: Black
So far, my second skin! I have lost a little weight and am trying to keep the thermostat down due to electric costs. I'm also elderly, so needing a little bit more warmth this winter is a must. I bought this set and I do not regret. Comfortable, non-itchy, easy to wash in machine on cold, and I dried them on the low setting. Fit perfectly as I am 5'7", 185 lbs, high waisted, and bought XXL. My hips are just a few inches more than the XXL stated, but I took a chance and they do stretch and still comfortable. I'll probably buy another soon. ... show more

    • Comfortable | Soft | No bulk
Size: Medium Color: Black
Pros: - Comfortable - Soft, fleece lining - Thin, but will keep you warm - Not thick, bulky, or bunchy when worn under clothes Cons: - None! I have enjoyed wearing the thermal underwear because they are warm and comfortable. What I like is that they are not very thick or bulky to wear under clothes. The material is very similar to those of cheap leggings, but I feel that the quality of these are good. Overall, I am happy with my purchase and I would recommend. ... show more

    • Awesome quality warm layer
Size: Large Color: Dark Gray
Love, love, love!!! Fit is great and fabric is oh so soft. Kept me warm under clothes worn on recent trip to Alaska.

    • Ehhhh shirt is true to size, not the pants
Size: Medium Color: Black
Set is a mixed fit but still worked well for my trip. The shirt fit true to size and kept me warm in 10–20 degree weather under my jacket, but the pants ran small and didn’t fit as expected. I decided not to return it since the top was perfect and we were too close to leaving for our snow vacation.
