BAND SIZE: Standing straight up with an unpadded bra on, measure closely around the chest just under your arms, right above the bust. If your result is a fraction, round to the nearest whole number. (ex. 33.7" rounded to the nearest whole number, your band size is 34")
BUST SIZE: While wearing an unpadded bra, loosely measure around the fullest part of your bust. Round to the nearest whole number. (ex. 34.5” rounded up to the nearest whole number, your bust size is 35”)
CUP SIZE: Subtract your final Band Size from your final Bust Size to find your Cup Size. (1” difference = A Cup, 2” B Cup, 3” C Cup, 4” D Cup, 5” DD Cup)

Fit:Ultra-tight, second skin fit.
Digging, bouncing, and permanent damage—breast pain isn't picky about size, ladies...it happens to all of us. So whether you're an A or a DD, the right support is paramount to a pain-free workout. We worked with Dr. Joanna Scurr, the authority on biomechanics of the female body. Talked with every day athletes just like you, and tested hundreds of prototypes. The result is the revolutionary Armour Bra™, sized to fit both band and cup for the perfect performance fit—even for A-cups. No more excuses. No more compromises. And, most importantly, no more pain and potential damage. That's a beautiful thing.
