QR-7 Pearl
Our QR series of coverstocks is known for creating a strong footprint to the lane surface.
The QR-7 Pearl coverstock complements the QR-7 Hybrid coverstock. The Hybrid version gave us mid-lane traction with continuous back end predictability and now the QR-7 pearl coverstock gives us length with backend angularity and continuation.
