US Patent 11382366 Wearable airfoil

A wearable arm airfoil garment for reducing the cyclist aerodynamic drag. The wearable arm airfoil includes a front bluff elastic band having ends connected at two anchors, with a first anchor located proximate to the wrist, and a second anchor located proximate to the shoulder. The front bluff elastic band stretches along the radius bone and the humerus bone, between the two anchors. The airfoil also is a stretchable garment material, the garment material wrapping around the arm and over the band from wrist to shoulder, with a body conformable stretchable bodice. In one example, the arm airfoil includes a shirt torso airfoil.
