Efficiency is king when you're on the bike, and De Marchi's Corsa Jersey is intended to be as streamlined and aerodynamic as possible. Ever up to the task, De Marchi's designers met their goal using a smooth blend of Italian materials that work to support your torso, move moisture away from your skin, and keep drag to an absolute minimum. For the construction, De Marchi used a soft multifilament fabric with an airy composition and low weight. This material breathes better than most nylonLycra blends, and it rapidly transfers moisture away from your skin to its quick drying outer layer. The fabric also stretches in order to wrap and support your upper body and arm muscles while in the saddle, and is constructed with De Marchi's ergonomic contour fit for maximum mobility without irritation. The jersey is finished with a full length locking front zipper, three rear panel pockets, and subtle but effective reflective details. At the chin, a soft internal flap prevents zipper irritation. The Corsa also has full UPF 50 sun protection to reduce the effect of skin damage caused by summer rays when you're out on the road for long rides.
