Under Armour Womens Infinity Mid Impact Sports Bra (Style S9H5)

Our review of the Under Armour Womens Infinity Mid Impact Sports Bra finds it best suited for active women who need reliable, targeted support during medium-impact workouts. The single biggest reason to buy is the bra's combination of structured support and breathability: the injection-molded pad and mesh side panels work together to reduce bounce while keeping the fit lightweight and well ventilated during cycling, weight training, and boxing sessions. It balances comfort and function without feeling bulky, and the front hook & eye plus convertible straps make getting dressed simple.

Key Features

• Strategic support: Designed for medium-impact activities, the bra delivers targeted containment that helps reduce movement during cycling, weight training and boxing.
• Injection-molded pad: The new pad uses a patterned, aerodynamic shape to create a lighter, more contoured fit without sacrificing coverage.
• Mesh side panels: Breathable side panels increase airflow and help wick heat away during sweaty sessions.
• Encased elastic band: A smooth, sweat-wicking elastic band provides a comfortable underbust fit and fastens with an easy hook & eye closure for quick changes.
• Convertible straps: Front adjustable straps can be worn straight or crossback so users can adapt support and shoulder comfort to different activities.

Who It's For

The Infinity Mid Impact Sports Bra is aimed at women who do medium-intensity training and want a bra that feels supportive without the bulk of a heavy compression style. It is a solid pick for cyclists, people who lift weights, and those who box or take cardio classes where control and breathability matter.

Those who need maximum compression for very high-impact running or prefer minimal structure for low-impact yoga may want a different style; similarly, shoppers seeking a bra with removable cups or wire support should look elsewhere.
