Under Armour FAQ

Who makes Under Armour?

Under Armour was founded in 1996 by Kevin Plank, a former University of Maryland football player who wanted a shirt that would not stay soaked with sweat at practice. The company is headquartered in Baltimore and is known for moisture-wicking sports apparel.

How does Under Armour kids sizing work?

Baby sets come in 12, 18 and 24 months, and little kids' styles in 4Y to 7Y, including 6X. Youth sizes use letters: on our listings YSM is shown as size 8, YMD as 10–12, YLG as 14–16 and YXL as 18–20. Some jackets are sized 8Y to 16Y instead.

Does Under Armour swimwear have sun protection?

Yes, on the listings that state it. Boys' surf shirts, volley shorts and swim sets are listed as UPF 50+, and girls' bikinis, rashguard and swim short sets are listed as UPF 30 or 30+, covering the skin under the fabric. Compare girls swimwear and boys swimwear.

Which Under Armour jackets suit cold or wet weather?

Some Under Armour jackets list UA Storm technology to repel water, and insulated styles add warmth for winter, while windbreakers are lighter layers for fall. Check each jacket's features, then compare boys coats and jackets and girls coats and jackets.

What are Under Armour Boxerjock briefs?

Boxerjock is Under Armour's boxer brief, sold to boys in packs of two. They list smooth HeatGear fabric with four-way stretch, a sweat-wicking quick-dry finish, chafe-free seams and legs designed not to ride up. See more in boys underwear.
