ANOTHER SEASON, ANOTHER FASTEST JERSEY WE'VE EVER MADE

Updated fabrics on the front and back showed a 2 watt gain in the wind tunnel. But it's not just aero; it's also extremely light, coming in at just 103g. That's about 40g lighter than a standard jersey and almost as light as our Climber's Jersey.

Features:
• The most aero jersey ever made
• Velocity dimpled fabric on front
• 3D mesh on back to prevent overheating
• Mesh arm bands
• Compression band around waist keeps 3 rear pockets in place
• Silicone gripper elastic
• Full-length YKK® Camlock zipper
• Reflective heat-transfer viz strips

All sales are final.
