Why the HSIA FlexCore and Powermove a Workout Game-Changer:

High-Impact Bounce Control & Supportive Lift:

 

Engineered for Intense Movement:

Built for running, aerobics, and cardio. The ultra-elastic underband hugs your ribs firmly, absorbing shock and providing 360° stability to eliminate painful bouncing.

 

Wire-Free All-Day Comfort:

Enjoy professional-grade high support completely free of digging underwires for a secure hold that feels natural yet incredibly powerful.

 

Full-Coverage Security & No-Spill Silhouette:

 

Friendly to Big Breasts:

The full-cup design completely encompasses your bust, smoothing side bulges and preventing top or side spillage so everything stays perfectly in place.

 

Skin-Friendly & Anti-Showthrough:

Crafted from premium, opaque fabric with official OEKO-TEX Certification for skin safety. It offers smooth concealment without any show-through.

 

3D Fixed Cups & Easy Laundry Maintenance:

 

Zero Pad Shifting:

Integrated 3D molded, ultra-thin fixed inner cups will never slide, bunch up, or move out of place while you are sprinting or jumping.

 

Laundry Day Hero:

No more re-inserting or fixing twisted pads after washing. These cups maintain their shape permanently—just throw it in the wash and tumble dry.

 

Advanced Dual-Zone Moisture Management:

 

Zero-Sweat Sensation:

Both the outer fabric and inner lining feature moisture-wicking technology to pull sweat away instantly and prevent a sticky, suffocating feeling.

 

Racerback Mesh Ventilation:

The racerback design combines structural stability with a targeted mesh cooling zone, releasing heat where you sweat the most.

 

The Precision Fit System for Fuller Busts:

 

6-Stage Padded Relief Straps:

Innovative 6-stage adjustable hook-and-loop straps allow you to fine-tune your lift. Extra-wide, plush cushioned lining puts an end to shoulder digging.
