Todd B.wrote a review of Assos MILLE GT Jacket ULTRAZ Winter - Men's on October 22, 2018
Familiarity: I've used it once or twice and have initial impressions
The new Ultraz version of the Mille GT jacket is a great winter jacket. I had the bonka.6 Mille jacket but sold it because it was too loose of a fit at the waist. I was about to order the bonka.6 Cento, when this version of the Mille GT appeared on Assos' website. I was a little concerned at first because of the "Mille" designation - thinking it was going to be just as loose of a fit as the bonka.6 Mille jacket. It isn't. It is a little more form fitting which is what I was hoping for. I can't compare it to the bonka Cento as I have never tried that one, but the Ultraz is certainly more form fitting than the bonka Mille. Not too tight though. Perfect in my opinion.
The protection, insulation and features are incredible for this jacket at this price. The built-in neck/face warmer is a great feature as you just have to grab your favorite hat and you're set.
I rode 30+ miles with this jacket with the following kit: bonka tights, winter skin foil, Ultraz jacket, Stinger cap, bonka gloves, and winter booties. Temps were 30's to low 40's Fahrenheit. I never felt the chill anywhere. When the temp got into the 40's towards the end of my ride, I had to halfway unzip the jacket a few times to ventilate.
I'm 6'2" and 190 lbs. and I wear an XL in Assos gear all the time. I can't wait to wear this for fatbike season this winter. Given my experience in the 30-degree weather, I can easily see wearing this jacket with just the winter skin foil in temps down into the 20's.
