Unapologetic by Design. Own every layer. Master Every Move with the new Under Armour Women’s HeatGear® Baselayer.

Designed for you to keep cool under pressure and power through every moment.

Ella Eiveren doesn't pick between polished and powerful. She shows up as both. Hair in rollers. Mid-manicure. Mid-rep. From the Philippines to London, from runway to her own Pilates studio, she's built a life on her own terms. Her UA Baselayer moves like a second skin: lightweight, breathable, and cool through every transition. She brings her mentality. HeatGear® handles the rest.

Cristina Stanciu lifts for Belgium. And for herself. Strength isn't just what she does. It's who she is. Her HeatGear® Baselayer locks in, compresses, and supports. Built for the kind of power that doesn't ask permission. Figure-hugging. Confidence-fueling. Ready for every lift and every grind. She's unbothered. Unbreakable. Unapologetic.

Sienna King doesn't fit into boxes. She breaks them. Model. Actress. Queer identity advocate. Unlike her boxing gloves, books, protein shakes, and lip gloss, her UA Baselayer keeps it all together with a compression that engages and a fit that performs. She’s unbothered, unapologetic, and fully in control without breaking a sweat. That's some HeatGear® confidence.
