Mixed Martial Arts fighters are stepping up for a great cause.
Female MMA fighters — including Ronda Rousey, Felice Herrig, Liz Carmouche and Julie Kedize — are donating signed sports bras for charity, with proceeds going to Keep A Breast.
The nonprofit organization is dedicated to eradicating breast cancer for future generations and has received many donations from MMA fighters, including Rosie Sexton‘s top and shorts.
As of mid-day Friday, Rousey’s bra (pictured above) has the highest bid. It’s going for $340 (plus shipping).
