Our review of the Under Armour Womens Infinity Mid Impact Sports Bra finds it best for active women who need dependable support for medium-impact training without bulk. The bra delivers its biggest advantage in targeted support and breathability: an injection-molded pad and mesh side panels work together to give a streamlined, lighter feel while keeping vents where sweat builds up most. In testing this design during cycling and weight sessions, the fit stayed secure and the encased elastic band with hook and eye made it easy to remove after a sweaty workout.
Key Features
- Strategic support: Tailored for medium-support activities like cycling, weight training and boxing to reduce bounce while maintaining freedom of movement.
- Injection-molded pad: A new molded pad with a strategic pattern creates a more aerodynamic fit and a noticeably lighter feel during activity.
- Breathable panels: Mesh side panels provide added ventilation where sweat collects to help keep the skin cooler during longer sessions.
- Sweat-wicking band: The smooth, sweat-wicking encased elastic band helps manage moisture and has an easy hook and eye closure for quick on and off.
- Convertible straps: Front adjustable, convertible straps can be worn straight or crossback so users can customize support and range of motion.
Who It's For
The Infinity Mid Impact is aimed at women who do medium-impact workouts such as cycling, steady-state cardio, weight training and boxing and want a balance of support and breathability. It suits those who value a lighter padded shape and adjustable straps for a customizable fit.
Women who need maximum compression for high-impact running or those who prefer minimal padding may want to consider a high-impact or unpadded alternative, since this bra is designed specifically for mid-impact comfort and versatility.
