Under Armour HeatGear Authentics Women's Shorts Using HeatGear technology, Under Armour's original performance baselayer materials, the HeatGear Shorts will be the ones you put on first and take off last. They have made them extra comfortable by wicking sweat and stretching so you can move no matter what. Made from HeatGear materials, the Authentics Shorty are a super-lightweight, breathable pair of shorts, with the ability to keep you dry and comfortable when you're on the move. Not only this, but HeatGeat technology works to keep you cool when things begin to heat up, meaning you remain comfortable and ready for whatever your workout throws at you.
