The structural foundation of the GR Vertex relies on a race-grade, high-density cowhide leather frame designed to endure intense frictional heat and resist tearing during high-speed slides. The sleek black torso layout is broken up by sharp geometric chest and leg accent streaks, highlighted by precise matching contrast safety stitching that runs across every structural seam. To facilitate complete fluid movement when hanging off the bike through chicanes, heavy-duty accordion leather stretch panels are seamlessly integrated right above the knee joints and across the lower lumbar region.
Impact protection is managed seamlessly via internal and external defense systems. Low-profile, CE-approved energy-absorbing armor inserts sit tightly against the shoulders, elbows, and knees to shield critical bone structures from blunt force. Externally, stylized, impact-resistant composite knee shields provide smooth deflection during track slides. The entire assembly is reinforced using high-tensile multi-row safety stitching, ensuring the suit maintains structural integrity under intense physical duress.
