Under Armour HeatGear® No-Slip Waistband Full-Length Leggings Women's. HeatGear® is our original performance baselayer—the one you put on first and take off last. So we made it extra comfortable by wicking sweat and stretching so you can move no matter what. Super-light HeatGear® fabric delivers superior coverage without weighing you down. Material wicks sweat & dries really fast. 4-way stretch construction moves better in every direction. Ergonomic flatlock seams deliver a comfortable, chafe-free fit. High-rise UA No-Slip Waistband for optimal coverage & support that stays put with every move you make. Side drop-in pocket. The contrasting stitched detailing and Under Armour branding combine with the full length leg style for a finished design.
