Active Sports Bra by on running

Size Inclusion

This sports bra is available in the worst sizing and isn’t even available for D+ cups so it’s perfect for runners without large boobs. If you have big boobs, sorry, this bra isn’t for you.

How it Feels On

Great if you aren’t running! Most sports bras that lack support do though.

Getting it On and Off

Average.

How it Looks

It looks pretty dang good. Unless you run in it. Then you look ridiculous.

The First Test

I don’t hate myself to run in this.

Was there chafing?

Your boobs will knock you out before they chafe if you run in this. If you don’t want a tension headache, don’t run in this.

Was there bounce?

It was all bounce.
