Frequently Asked Questions

Is this sports bra suitable for high-impact combat sports training?

Yes — the Crossback Sports Bra is designed specifically for the high-impact demands of combat sports. The support construction handles boxing bag work, pad work, and the dynamic movement of Muay Thai and BJJ training more effectively than standard low-impact or yoga-focused sports bras. If you train at high intensity with significant upper-body movement, a high-impact support level is essential for both comfort and long-term tissue health.

How do I determine my sports bra size?

Measure your band size (just under the bust, at your ribcage) and your bust size (fullest point of the chest). Standard sizing XS through XL typically corresponds to band sizes 28–38. Hayabusa sizing runs athletic — if you prefer more room, size up. A properly fitting sports bra should feel snug across the ribcage without being restrictive on breathing, with straps that don't dig in or slip.

Can I wear this under a BJJ gi or rashguard?

Yes — the Crossback Sports Bra is appropriate to wear under a gi jacket or rashguard for BJJ and MMA training. The flatlock seam construction prevents the friction irritation that regular seams cause during extended rolling. The removable pad option allows a streamlined profile under close-fitting training tops.

How do I care for this sports bra?

Machine wash cold on a gentle cycle. Air dry or tumble dry on low heat — high heat degrades the support structure and elastic over time. Remove the pads before washing to prevent deformation. Do not iron. Wash after every training session to prevent sweat residue from breaking down the fabric and causing odour.
