Under Armour HeatGear Racerback Girls' Sports Bra comes in as a fitted, racerback training piece with a $20 price tag and a style number of 1383758. The design uses HeatGear fabric, and Under Armour says it is built to wick sweat, dry fast, and stay light.

Fit And Fabric

The product page lists 87% polyester and 13% elastane, plus a double-lined build with no padding. Under Armour also calls out a classic pullover design, a racerback cutout for ventilation, and odor control technology.

That puts the piece closer to performance underwear than casual swimwear, despite the word heatgear. The brand's HeatGear line is presented as lightweight, ventilated clothing made to keep wearers cool in hot conditions.

Under Armour's Product Line

Under Armour's official site places HeatGear in a wider women’s and girls’ performance range, including fitted and compression apparel. A girls' HeatGear racerback sports bra is sold alongside other girls' one-piece swimsuits such as UA Polka Party at $40.

Where It Fits Best

Under Armour, Inc. is headquartered in Baltimore, Maryland, and the brand is sold through the company’s US store. The girls' sports bra suits a buyer looking for a fitted training layer with a racerback shape, a 87% polyester and 13% elastane mix, and a low-cost entry point.

Compared with a girls' one-piece swimsuit at $40, the $20 sports bra sits at the lower end of the brand's swimwear and training range. For families comparing HeatGear and one-piece options, the difference is mainly in cut, coverage, and use.

Bottom Line

HeatGear Racerback Girls' Sports Bra is a simple, numeric product story: $20, style 1383758, 87% polyester, 13% elastane, and no padding. The model works best as a fitted girls' training layer, not as a swim suit or a fashion top.
