Under Armour UA Infinity High Sports Bra - High Impact Support Bras

Our review of the Under Armour UA Infinity High Sports Bra finds it best suited to athletes and regular runners who need dependable, high-impact support without sacrificing breathability. The single biggest reason to buy is the combination of molded, PU injected padding and a structured band that work together to hold everything in place during dynamic movement. The design balances containment with a next-to-skin HeatGear feel and convertible straps for a customizable fit, making it a practical choice for high-support workouts.

Key Features

• Strategic support: Molded, injection-molded one-piece padding provides targeted shaping and keeps movement controlled during high-impact activities.
• Convertible straps: Front adjustable straps that convert to a criss-cross back let the wearer fine-tune lift and security for different sports or preferences.
• Breathability: Mesh panels and a front mesh insert increase airflow to reduce heat buildup during longer runs and intense sessions.
• Easy on and off: A smooth, sweat-wicking band with a hook and eye closure simplifies dressing and ensures a snug underbust seal without irritation.
• Fast-drying fabric: HeatGear material wicks sweat quickly and dries fast to maintain comfort during back-to-back training days.

Who It's For

The UA Infinity High Sports Bra is aimed at people who regularly do high-impact exercise such as running, court sports, field sports, and aerobics and who prioritize containment and a secure fit. Runners and athletes who need a bra that holds breasts in place during dynamic movement will appreciate the molded padding and structured band.

Those seeking a lightweight, minimal-coverage option or someone who prefers a very roomy or forgiving fit should look elsewhere, as some customers report the bra runs on the firmer side and may feel small for some body shapes despite its adjustable straps.
