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.


  • Warp-knit RX Heavy fabric developed to wick moisture and add insulation while still highly flexible
  • 2L windproof and highly breathable softshell NEOS Ultra is constructed with a PU bonded membrane, added along the leg panels for increased water-repellency
  • Double-layer twinDeck fabric construction boosts insulation using a combination of NEOS Ultra and RX Heavy textiles
  • Asymmetrical-stretch warp-knit RX Light fabric provides light insulation and boosts comfort in high-flex areas
  • Featuring new black colorway, the MILLE Winter Insert uses proven 8mm of memory foam to nestle at the intersection between comfort and performance
  • Perforated 3D waffle foam provides lightweight breathability
  • Patented goldenGate technology interrupts stitching along both insert's side panels, allowing a more three-dimensional freedom of movement
  • Y7 Frame Carrier Bib Tech — wide, flexible bib straps converge at the upper back in a Y-shape design for a flat, stable structure that doesn't irritate the shoulders
  • Stabilizatior V3 is a dorsal stabilizer in solid mesh with limited vertical stretch, also includes UMA GT line graphics and climaCode
  • Reflective bands placed on the backs of the calves boost visibility
  • RegularFit is optimized for total comfort in the riding position, with a more relaxed cut than the second-skin racingFit
  • 81%PA 18%EA 1%PL composition

    Defective? and Not Warm

    This product is both defective and not warm. As a long time ASSOS customer, I'm both surprised and disappointed with ASSOS. First, the defect. After only 15 rides, the back side (where it connects with the seat) was seriously pilled (frayed). It was quite gross. I was using a Selle Italia Superflow, which is a common road bike seat, on my Colnago C64. I did research and found six other reviews that complained of the same issue. So this is a known problem. If this is a known problem now, it should have been a known problem in testing. So it was either inadequately tested or ASSOS know about the problem and sold it anyway. Second, Winter Warmth. This product is also not warm. It's just not warm. It's sold as a winter solution. My view is that ASSOS management drank its marketing department's Kool Aid (BS for foreign readers) on this product. They are "rated" to -4degC to 8degC (25degF to 46degF), but they are NOT WARM for me below approx. 4deg+C. I am 5' 9" (175 cm) at 155 pounds (71kg) and I ride >6,200 miles (approx. 10,000 km) per year for 12 months of the year in the Washington DC area. I rode them to -4degC and up to 8degC on 1, 2, 3 and 4 hour rides. They are cold at the beginning and never get too much warmer. The longer the ride, the colder they get. At below freezing after 3 hours, my thighs ached for the rest of the day! I realize that sensitivity to cold is personal. But not like this. I very much appreciate that ASSOS, through BikeTiresDirect, accepted a warranty return. Thank you. I also purchased a different set of ASSOS winter tights that I hope will work because I still have confidence in ASSOS. I don't normally write reviews, but I believe that my winter cycling friends must be informed about this product.

    Impressive winter time bibs

    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.

    Worth the investment

    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.
