Our detailed wind tunnel tests suggest that the Project 1.0 suits are our best set. However, for those who have already invested in another suit, the BASE Z3 under-sleeves might be the best alternative. These aerodynamic under-sleeves have been developed with the same patented technology as the Project 1.0 suits and are designed to be worn under your existing suit. They have been proven to reduce drag and make the Brios, Sonic, and Verano suits even faster.
