Under Armour Size, Fit and Durability Issues — Review

Data basis: I reviewed dozens of written buyer comments and several hands-on video demos collected between January 2024 and January 2026, with most feedback coming from written reviews supported by short video demonstrations.

Top failures

Do they run true to size?

Sizing drift — Many buyers find the labeled size does not match the actual fit, creating a regret at first wear.

Usage anchor — This appears immediately at first try-on and can worsen after the initial wash.

Category contrast — This is worse than average for youth leggings where consistent sizing is normally expected; buyers often must size up or exchange.

Will seams or fabric irritate during play?

• Early sign — Some kids report a rubbing sensation near the inner thigh during running or soccer practice.
• Frequency tier — This is a secondary complaint that appears repeatedly but not universally.
• Likely cause — Raised seams and tighter cuts during active movement increase friction more than typical.
• Impact — Chafing reduces comfortable active time and can force earlier outfit changes.
• Fixability — Some buyers mitigated the issue with seam-taping or wearing liner shorts underneath.

How do they hold up after washing?

• Early sign — Color fading and light pilling often show after a few machine washes.
• Frequency tier — This is a primary issue for long-term owners and appears repeatedly across feedback.
• Cause — Elastic and fabric structure seem to lose tension faster than category peers.
• Impact — Loss of shape leads to sagging legs or a stretched waist, shortening useful life.
• Attempts — Buyers tried cold wash and air dry, which slowed but did not stop deterioration.
• Hidden requirement — Expect extra care (gentle wash, hang dry) to avoid accelerated wear, a requirement not obvious from the packaging.

Do they deliver the promised warmth and wicking?

• Performance gap — The brushed grid interior traps heat, but some users still reported dampness after intense play.
• Frequency tier — This is a secondary but noticeable pattern for active kids during long sessions.
• When it shows — The issue appears during high-exertion activities or long outdoor use in cool, wet conditions.
• Why worse — Competing mid-range baselayers often balance warmth and quick-dry properties better.
• Impact — Dampness can make kids feel colder and reduce comfort during breaks.
• Attempts — Buyers layered up or used a waterproof shell to compensate for moisture hold.
• Fixability — Performance improves with lighter activity or shorter wear time, but not fully for intense use.

Excerpt: "Waist felt too tight, then stretched out after one wash." — primary pattern

Who should avoid this

• Parents needing consistent sizing — If you want a safe first-fit purchase, this product's sizing variance exceeds normal tolerance.
• Active kids in long sessions — If your child does long sports sessions, seam friction and dampness create real comfort problems.
• Buyers who want low-maintenance clothing — This product often requires gentler washing and special care to maintain shape.

Who this is actually good for

• Short-play users — If leggings are for short outings or light activity, the warmth benefit can be useful despite other flaws.
• Buyers who can size up easily — Families willing to order a larger size or exchange can avoid the fit regret.
• Careful launderers — If you always wash cold and hang dry, the durability issues are less likely to matter.

Expectation vs reality

• Expectation (reasonable for this category) — Youth leggings should fit labeled sizes and survive regular washing.
• Reality — This product more often shows sizing drift and earlier wear, causing returns or extra care.

Safer alternatives

• Choose consistent-fit brands — Prioritize sellers with clear size charts and reliable fit notes to avoid sizing drift.
• Look for flat-seam construction — Seek leggings advertised with flat or bonded seams to prevent chafing during activity.
• Prioritize wash-tested labeling — Prefer products that explicitly state colorfastness and stretch retention after multiple washes.
• Layer strategy — If you keep this product, plan for a moisture-wicking inner layer to address dampness during intense play.

The bottom line

Main regret — The combination of inconsistent sizing and early wear is the strongest reason to consider alternatives.

Verdict — For buyers who need reliable fit and low-maintenance durability, this product presents higher-than-normal risks and is often worth avoiding.
