Aerodynamic sleeve tech, inspired by our aero socks, cuts airflow and reduces drag. A flexible, second-skin torso keeps you locked in and moving freely when the pace surges.

Thermal fabrics with a fleece-lined interior keep you warm and dry on cold mornings and long miles. Moisture management works fast, so you stay focused—not frozen.

Clean seam work and a refined fit remove irritation, even in aggressive aero positions. Designed for comfort across hard efforts, base miles, and everything in between.

For those chasing even more speed, pair with our Aero Bib Tights

Warm enough to ride solo through dry spring and autumn days, thin enough to layer cleanly under the Insulated Gilet or Lightweight Jacket when the wind turns sharp or the rain starts.

Top of the range winter fabric. Fleeced fabric with PFC Free DWR M™ treatment. Providing insulation, comfort and water repellency.
