Born from balance and made for movement, The Equinox is the strapless performance bra that unites strength and grace in perfect form.

Designed for women who embody every side of themselves, The Equinox delivers a secure sculpting fit through ZIREYA’s signature enclosure system. No slipping. No constant adjusting. No sacrificing beauty for performance.

Unlike traditional strapless designs, The Equinox is made without silicone grip strips that shift or slide when heat and sweat rise. No wires. No digging. No discomfort. Sewn in pads remain perfectly in place, creating smooth support without bunching, folding, or movement.

Inspired by the celestial moment when day and night stand as equals, this striking black and white silhouette represents harmony, confidence, and the power of being whole.

Crafted in a bold contrast finish with breathable textured fabric, The Equinox moves effortlessly from workout to nightlife, from active moments to elevated style.

Confidence stays on. Straps stay off.

How to Measure

Measure your underbust snugly just beneath your bust, keeping the tape parallel to the ground.

Measure your bust at the fullest point, relaxed and standing upright.

If you fall between sizes, size up for a more relaxed fit or size down for a firmer hold.

Measurements are industry standard ranges and serve as a placeholder until final techpack measurements are confirmed. The Unbound Series is designed to hold without straps — a precise underbust fit is essential for optimal support.
