    Leggings deliver high performace sweat wicking and are very comfortable. Even though it is heat gear, they keep you reasonable warm but can keep you cool as well. Great product, will be purchasing the cold gear leggings.

    These were a great addition to my football gear for the colder nights. It also helps protect against turf burn on exposed legs from gear.

    It's like another layer of insulation for when I'm working outdoors for long periods of time.

    The leggings fit true to size and the material is a little thicker than other leggings in which is a benefit in reference to keeping you warmer. Price is reasonable when on sale. Comfortable feeling and length is perfect.

    These leggings are perfect for wearing under hockey gear. They provide a layer between my skin and the equipment to help prevent any infection and to keep the equipment fresher.

    Fits true to size, the compression helps keep you cool during workout, also keeps your muscles and joints tight helping to avoid fatigue. Great product , quick shipping, and reasonably priced.

    These tights are outstanding and can be worn the year round. I have worn other "base layers" over the years and none of them compare favorably with Under Armour. I would not consider wearing any other product.

    Not the first pair I have purchased for my boy 7 myself. Fit well, keep their shape over time. Only down side is missing the sales...
