The Nero XII Jammer is designed for the best competitive athletes in the world. It excels in the two most important factors of a jammer: fit and compression. The Nero XII fabric is designed to reduce drag, streamline body position, and improve performance.

• Patented seam welding technology:
    - Welded seams create 50% less drag than a conventional over locked stitched seam.
    - Lock seam: 3 layer folded bonding technique.
• 3-dimensional anatomically refined fit.
• Internally welded core stability panels:
    - Internal panels support abdominal function and enable you to hold a better body position in the water.
• Nero XII fabric:
    - Enhanced compression, improved power, and elasticity.
    - Lightweight.
    - 56% more compressive fabric.  
    - Double the fiber percent than a standard performance suit.
    - Increased lateral compressive force.
    - Increased stretch in the vertical direction to improve range of motion.
• Imported.
