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. Superlight, smooth HeatGear® fabric holds you in and stays up while on the run. Material wicks sweat & dries really fast. 4way stretch material moves better in every direction. High rise waistband with interior drawcord for a optimal coverage & a perfect stayput fit. Side drop in pockets. Free cut hems for added comfort. Reflective details for lowlight runs. Odour control technology minimizes odour. Ref: 1383418025
