We built this piece as a crop top with the interior structure of a high impact sports bra. Molded cups sit inside flat-seamed linings to maintain separation while you run. The dark grey four-way stretch fabric extends down the ribs into a broad underband that anchors the hem.

  • Molded cup interior. The front is built with molded cups set into smooth inner lining seams to give full coverage without collapsing during high impact movement. They hold their shape through repeated sprints and wash cycles.
  • Racerback cutout. The back narrows into a classic racerback profile over a wide keyhole cutout. This pattern clears your shoulder blades for full rotation and lets hot air escape as you work.
  • Longline underband. The knit body drops below the bust line into an elongated lower panel. This wider base spreads tension evenly along the torso so the top stays anchored without riding up.
  • Care and wash. Wash this dark charcoal piece in cold water on a gentle cycle to protect the molded cups and elastane stretch. Lay it flat to dry instead of using high dryer heat.
