First up is the 90g Climbers' jersey, which is made from the 'super light' Strada Light 3D mesh fabric and is cut to eliminate excess flapping in the wind. Castelli reckon, because of the mesh material, it's their quickest drying jersey yet and sacrifices 3 watts at 40km/h compared to the Aero Race jersey.
The matching Inferno Bibshorts are constructed from seven different fabrics and, like the jersey, is claimed to be their coolest and lightest yet. They contain titanium dioxide (the active ingredient in sunscreen) but because some fabrics are open meshes, they recommend you still use cream on the front and side of the legs. The seamless Progetto X2 Air seatpad, used in Castelli's Body Paint shorts, is also used here.
Pricing hasn't been confirmed yet for either garment
They've both been seen in the recent mountain stages of this year's Giro, worn by, amongst others, Ryder Hesjedal, who holds second place going into the final week. It will be some time though before the public can get their hands on them - they are part of the summer 2013 collection, which means next spring at the earliest.
