Assos - Mille GT Ultraz 3/3 Jacket S11 - Men's - Foundation Green

The Mille GT Ultraz 3/3 Jacket S11 is designed to be able to take on even the most extreme winter conditions with uncompromising protection and long distance comfort. Updated with advanced softshell technology and a refined fit that offers maximum warmth and complete stormproofing and improved breathability for the coldest rides of the year. 

At the core is the all-new AIRBLOCK-EVO.888 softshell, a highly elastic, stormproof barrier that conforms to the body while blocking wind, rain and freezing air. Beneath it, a new thermal grid textile traps insulating air pockets while actively managing moisture to keep you dry and warm. The sleeves now combine insulation and softshell protection into a single-layer construction, reducing bulk and simplifying layering with winter base layers or Ultraz gloves. The result is a total protection that maintains comfort without excess volume, even during all-day efforts.
