Lifespan Bra Calculator 

The She Science Bra Calculator will help you determine whether or not you are due for a new sports bra.

One of the most common questions we get at She Science is "How long will my sports bra last?” or "How do I know if I need a new sports bra?”. If you've had your sports bra for a while, it’s probably worthwhile using this Bra Calculator to determine how much longer your sports bra has left to live before it stops doing the important work of protecting your body during a workout.

Using two or three sports bras at one time in a rotation will improve the lifespan of your sports bra. By rotating your sports bras, you are giving the materials longer to rest between workouts. She Science recommends having at least two sports bra on rotation to reduce wear-and-tear and therefore save you money.

Leading sporting manufacturers suggest that a sports bra will last a year (at most) if it is worn and washed twice per week. The accepted amount of time before a sports bra becomes ineffective is any time after 4680 minutes of vigorous activity. We certainly don’t expect you to crunch the numbers yourself - simply tap in your date of purchase, number of workouts per week and average session length. The Bra Calculator will calculate how much life is left in your Sports Bra.
