Description
Crush the winter cycling season with the bib tight built to provide you with a warm, comfortable ride no matter how cold.
To succeed during the harsh winter months, improve your rides with winterproof textiles to deliver unmatched levels of insulation, breathability, and weather resistance. With double-layer protection throughout and a membrane-backed front panel, the Assos Men's MILLE GT Ultraz Winter Bib Tights stand in as the most protective bib tights in intense cold-weather conditions.
Constructed with highly insulating brushed-back RX Heavy with an added second layer on the outside for added protection. For this twinDeck construction, Assos put their NEOS Ultra textile to the test — an ultrathin 2L softshell with PU bonded membrane that's water-resistant and 100% windproof. With a design like this, the element-facing section of your legs and glutes remains protected from the snow, rain, wind, and low temperatures that winter months are known for. An added feature of RX Light makes up the backs of the legs, delivering increased breathability and comfort in this high-flex zone.
With the regularFit category, these tights are perfected to provide a lightly compressive fit thanks to their double-layer design, but not as tight as the high-intensity racingFit apparel. Fabric panels flex with each pedal stroke, as they're both pre-shaped and sewn to fully wrap and support the upper leg muscles, knees, and calves while in motion. Every aspect of the the Assos Men's MILLE GT Ultraz Winter Bib Tights is designed simply to tackle anything that weather dares throw at you to interrupt your winter rides.

Reviews
First, I'd like to acknowledge the extremely subjective nature of rating winter clothing for warmth. I'm an ice climber and a skier that regularly recreates in temperatures below 0 F, so keep that in mind.
I've found all of the Utraz line to be incredibly warm given it's relative light weight and extreme low bulk. Most of my winter cycling takes place after work (i.e. in the dark) and I will happily wear my Utraz tights, jacket, and base layer for 2 hours +/- with no concerns. In fact, at much above 30 F, the Ultraz clothing can get to be a bit too warm, particularly if the sun is shining.
Ultimately, it's my hands and feet that turn me towards home during cold weather rides.
No high end cycling (or climbing or skiing or running etc etc) gear can be called "a steal", but given what we ask our winter gear to do for us, I gave the Utraz tights 5 stars and have been very pleased with their performance in weather that is really more suited for books and tea than cycling.
These are definitely a "Wow, these were disappointing" kind of product. Based on the description, I expected something that was significantly more suited for Winter wear. These don't remotely feel like they'd be good for Winter use, short of a layer that wouldn't fit below how they are, seeing their tightness. The chamois seems excellent, but never got to try it. The biggest detraction I found with these and the reason for which I ended up returning them, was the front portion of the bibs is barely above the waistline, which would inhibit keeping drafts out while riding.
Simple and solid performance in a winter bib, great functionality and fit, very comfy on long cold rides around 28-32deg, still very comfy and not too warm when mercury reaches 40-45deg. Excellent moisture management in wide weather variance.
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.
