As with the Corsa, construction and protection are top notch. The Vortice (pronounced vor-te-che, Italian for vortex) features a tough Lorica carcass with interlocking armored sections that completely encase the rider's calf, shin and ankle in nylon armor. The same Techno Tensioner system first seen on the Corsa is used to secure the redesigned upper panel, with another tensioner adjusting the lower shin. Because of its tighter tailoring, the side-entry zipper utilizes an expansion joint that assists in getting the zipper over the talus bone of the ankle. The external lateral and lower braces on each side of the ankle (redesigned with a slimmer and tighter profile and reinforced with fiberglass) work with the new upper panels to provide improved ankle support.
