The mongoose or il mangusta in Italian, is the Assos mascot and in its honor comes the SS.mangusta jersey. Plenty of focus went into moisture management through wicking perspiration and ventilation. If you can master these two things, then true body temp regulation can be achieved. Type 151 fabric was borrowed from the Mille jersey for this purpose. Beyond regulating body temp, it is soft, comfortable and provides UV protection.
Full zipper front adds another way of regulating body temp. 3 pockets and an additional zipper pocket take care of storage. The bottom back of the jersey has the familiar elastic hem. Assos's AEPD anatomical cut is designed to fit while riding or assuming the cycling position. It is a relatively simple concept that makes all the difference.

Just FYI, Assos claims the fit of this jersey is between the SS.Uno and SS.Mille and ideal for athletic builds or "larger body types." I would say the fit is MUCH closer to the Uno than the Mille (I own both). Awesome, like all Assos clothing though.
