Primo Infinity Sports Bra Size Guide
Find your size below. The Primo Infinity Sports Bra is a lighter, lower-cut racerback bra with adjustable straps — built for lower-impact training, conditioning and warm-ups. The figures below are garment measurements taken flat across each panel. Choose by chest, then verify the underband, length and strap measurements suit your frame. The Infinity bra runs one size smaller than the Air bra so size up if you usually wear the Air bra.
