The NB Define Train Bra pairs best-in-class materials with flattering design language, providing medium support for dynamic training sessions and superior comfort for all-day wear.
Features
• Fitted silhouette is form-fitting, designed to feel snug against the body
• Medium support designed for training activities with intermittent bounce, such as weightlifting, boxing, gym workouts, interval training and cycling
• NB Dry fast-drying technology wicks moisture away from your body
• Removable pads for customizable coverage
• Pullover styling for easy on/off
• Elastic bottom band for support without restriction
• Built with Lycra® Adaptiv yarns, this style features premium NB Define fabric. NB Define fabric provides a comfortable second-skin feeling at movement and rest
• Size range engineered to support A-DD cup sizes
• Medium support, built for training: Sports are not one size fits all. You need the right level of support for your chosen activity. Our medium support bras are designed for the intermittent bounce of activities like gym workouts, cycling, weightlifting, and boxing
• All day comfort: We know that a sports bra isn’t necessarily being thrown in a gym bag or a locker the moment that your workout is over. The NB Define Train Bra offers all day versatility. It features NB Define. This premium fabric is built in part with Lycra® Adaptiv yarns and is designed to provide a comfortable second-skin feeling at movement and rest
• Pullover design: The NB Define Train Bra is a modern silhouette featuring a classic pullover design for easy on/off, with an elastic bottom band that offers support without restriction of movement
• Removable pads: Removable padding allows you to customize support and coverage to your level of preference, because perfect for one person, may be too much for the next
• Position the cups: Situate your breasts by bending forward and scooping them fully into each cup. The band should sit completely under your breasts, and your breasts should sit comfortably in the cups. If they feel forced together, spill out of the cups, or if the cups are digging into your skin, go up to the next size. If there’s gaping anywhere in the cups, try sizing down
• Flex the band: Stick two fingers underneath the band. You should be able to slide them around your ribcage without issue. If you’re unable to move them freely, try a size up. If there’s gaping or too much room, try a size down. Next, remove your fingers, and take a deep breath. This should be easy to do. If you feel constricted, size up. Lastly, raise your arms and check that the band doesn’t creep up as you move. If it does, size down
• Stretch the straps: Take note of how tight the straps are. They’re too tight if they’re digging into your shoulders and leaving grooves or redness after wearing. If your band fits right but your straps are too tight, consider trying an adjustable style instead. Next, pull your straps upwards. You should only be able to do this about five centimeters, or a couple of inches. If yours stretch longer, they’re too loose
• Move your body: Jog in place to ensure the bra is holding you in without annoying bounce and allows you to breathe normally. After you purchase, it’s time for the real test: working out in your bra. Take the tags off and exercise in it, while observing the band, cups, and straps. Your bra should feel like a supportive hug and not restrict your movement. If it’s not right, the New Balance Fit Promise™ for Sports Bras, which applies to select styles, will ensure you get the size and style bra that’s best for you
