Sizing tips

Between sizes?

For an athletic fit, size down. For a relaxed feel, size up. UA tech pieces usually run true to size.

UA vs Alo fit

UA pieces have a streetwear/athletic cut. Alo leggings are more compressive — size up for a softer hug.

Got questions?

How does Under Armour sizing run?
UA generally runs true to size with an athletic fit — fitted through the chest and waist, with room to move. Tech tees can feel slightly slim through the shoulders, so size up if you prefer a relaxed look.
How does Alo sizing run?
Alo runs true to size. Airbrush leggings stretch generously — size down for a sculpting fit. Airlift pieces are more compressive — size up if you prefer a softer hug.
I'm between two sizes — what should I pick?
For an athletic, performance fit: size down. For a relaxed, everyday wear vibe: size up. Trust the measurements — they don't lie.
How do I size for my kid?
Use the age guide as a starting point, but measure your kid's height and chest for accuracy. If they're between two sizes, size up — kids grow fast and pieces last longer.
What if the size doesn't fit?
15 days, free returns. Item must be new, unworn, with original tags. Contact us and we send you a prepaid label — easy.
How do I take my measurements correctly?
Soft measuring tape. Stand naturally. Measure over bare skin or a thin tee. Don't pull tight or leave loose — the tape should rest naturally against the body. See "How to measure" above for exact spots.
