When you're in it for the long haul, trust the UNDER ARMOUR® women's Fly-By running top to keep you comfortable through every mile. Large mesh panels on the sides and back keep it super breathable and light, while HeatGear® technology wicks away sweat so you stay dry. Raglan sleeves and flatlock princess seams promise a restriction- and chafe-free fit; reflective hits ensure visibility during the early-morning or late-night hours.

        Comments about UNDER ARMOUR Women's Fly-By Long-Sleeve Running Top:

        It just didn't work for me. Ordered the black and the color is not really black. It's more like a dark mousy grey. The fit was no good either! The collar doesn't stay straight, wide at the bottom and the sleeves are like for a giant! Couldn't wait to return it. Got a Nike similar product and I absolutely love it!

        Mesh back and mesh underarms help keep you cool, even in long sleeves with hand covering.
