I purchased these bibs to add to my winter wardrobe. In past winters, I almost exclusively rode in bib shorts covered with an older Assos overall type zip up bib. In spite of these zip up bibs being supposedly windproof, I found them not be keep me warm enough.
Today, my new Mille Ultraz Winter Bibs arrived in the mail. It was 38 degrees with strong winds. I went for a short 45 minute ride. I am impressed how much warmer these tights are versus my old Assos wintergarb. The foam insert was comfortable and combined with the front panel protection, kept this area warm.
I did not give these bibs a five star rating only because they are cut low in the midriff. I feel that they would be five star if they protected your stomach area better.
I rated them pricey, as of course, all Assos is expensive.
The fit & fabric are premium which results in warmth without restriction throughout. Good wind blockage also. Comfortable down to freezing temps although had to cover them with a shell just a few times throughout the winter, probably when I should not have been riding anyway.
