It's important that a sports bra is a perfect fit, only bras that are a good fit will be comfortable, but not only that they must prevent as much “bounce” as possible, therefore they should be “snug” but not uncomfortable

For chafing prevention and comfort, look for moisture-wicking fabrics such as Coolmax. Stay away from sports bras that are made of 100% cotton because once you start sweating, they’ll stay wet.

If you have a large chest and need a lot of support, look for sports bras with wide shoulder straps and racer back straps.

You will want covered seams to help prevent chafing.

When you try on sports bras, jog in place or do jumping jacks to test their support before you decide if it is for you. While you're bouncing up and down, the bra should minimize breast movement. If you are not sure if it is doing the job, call Underthetop.com  and we will advise you either before you buy or once you have tried it on.

After you find the perfect sports bra, don't hold onto it forever! You should replace bras after about 40 washes, when the elasticity is lost, or if your weight changes significantly. You can air dry sports bras to prolong the life of the moisture-wicking fabrics.
