    • Warm, comfortable, great value.
Very comfortable. Will be warm, especially when layered. Quality is excellent. Price is modest. No cotton. Stretches, and returns to proper shape. 3x fit me well. I wear both 2x and 3x shirts, and 2x would have been too small.

    • Soft and comfy
Super soft and warm. The fit is nice and snug. You can wear it underneath multiple layers or on its own. I washed it in cold water and high ish heat. It did not shrink in the dryer.

    • Comfortable and Warm
This is the most comfortable undershirt I have ever owned. Best part is it keeps you warm if not a little on the hot side.

    • Both Good and Bad
First, purchase the heavyweight version because the fabric is just thick enough to keep the body warm. Water wicking works, the elastic on the bottoms shrinks the most from washing, the rest of the fabric will slowly shrink after multiple washes, the stitching is of poor quality, the sizes for the tops tend to be too small compared to the bottoms that come in the pair, colors do not fade, whites are easy to stain. Overall, buy these if you're on a budget and are looking for something that is effective but will only last for several winters. ... show more
