The Women's FR Carbon Sleeveless Jersey is made from a new pattern, developed in conjunction with our pro team partners that is constructed to fit the body like a second skin on the bike The front, back, and shoulder panels as well as the collar of the new Women's FRC jersey are constructed of the soft and breathable Sensitivefabric. Fabric properties of superior wicking and elasticity are woven into the fabric and will not lesson over time. AeroLite cuffs are a low profile and soft solution to the sometimes harsh elastics found on summer jerseys. The AeroLite cuffs are interwoven with silicone gripper threads and create an aerodynamic fit. Asteria 2.0 is incredibly lightweight and is used on the side panels and shoulder reliefs for optimal aerodynamics. Host Carbon is used for the center rear panel where it limits the vertical stretch, stabilizing the pockets to prevent sag when they're loaded. Host Carbon has threads of carbon woven through it, allowing the material to be lighter, while maintaining its strength. Carbon has the added benefit of reducing electrical interference that can negatively affect performance. Under the arms, a micro mesh insert allows maximum breathability. A reversed full CamLock zip in front has a garage at the bottom to protect the materials from the zipper teeth and prevent snags. Three rear pockets with a fourth reflective CamLock zippered compartment allow ample storage and visibility for safety.
