Assos calls it body textile art.
With the introduction of the new Airblock 851 fabric (exclusively developed by and for Assos textile laboratory Lugano), Assos is taking wind-stopping fabrics for specific cycling application to a complete new level.

Designed as part of the Assos Winter outfit and intended to keep you comfortably warm in temperatures of 0-8 degrees celsius (32-46 fahrenheit), so ideal for an average UK winter's day.
The high collar and double layered wrist band helps to keep the cold out, and other practical features include the rear pockets and zipped safety pocket, elasticated rear hem and reflective strips.
