The MILLE GT Ultraz Winter Bibs are crafted from an arsenal of winter-ready fabrics for unparalleled insulation, breathability, and weather resistance. Featuring a double layer of protection throughout the garment and a waterproof membrane on the front, the Ultraz bib tights stand out as the most protective regularFit bib tights available.
We used the same brushed, highly insulating RX Heavy fabric as our Winter Bib Tights, adding a second outer layer for extra protection. For this twinDeck construction, we used NEOS Ultra, an ultra-thin, double-layer softshell fabric with a taped, waterproof, 100% windproof PU membrane, providing the exposed areas of the legs and seat with complete protection from snow, rain, road spray, biting winds, and cold temperatures. Like our Winter Bib Tights, the backs of the legs are made of RX Light fabric, providing increased breathability and comfort to this highly flexible area.
The Ultraz bib tights fit snugly in the regularFit category, which means they're slightly compressive thanks to the double-layer design, but not as tight as racingFit garments. Because they're both pre-shaped and stitched, the fabric components flex with every pedal stroke, providing a snug fit and full support for the upper legs, knees, and calves when in motion. The chamois is the proven MILLE Winter Insert, cleverly stitched into the RX layer only with reverse stitching for a seamless next-to-skin feel.
RX Heavy: Applied to the side in contact with the legs, this combed warp-knit fabric has been developed to provide exceptional comfort, absorb sweat, add high levels of thermal insulation and maintain extreme flexibility. 290 g/ m2 , eco-friendly water repellent and with odorControl system.
NEOS Ultra: Applied as a second layer along the leg panels, this patented, windproof, highly breathable double-layer fabric features a taped polyurethane membrane for additional water repellency. Weight: 190g/ m2 ; breathability: MVP 44,500g/ m2 / 24 h; water column: > 10,000 mm; elasticity: four-way.
twinDeck: Two-layer fabric construction that increases thermal insulation using a mix of NEOS Ultra and RX Heavy fabrics.
RX Light: Lightweight, asymmetrically stretch warp-knit fabric designed to provide lightweight insulation and increased comfort around the back of the knee. Weight: 205 g/ m2 , water-repellent, eco-friendly, and with an odorControl system.
MILLE Winter chamois: The revisited MILLE chamois with elastic interface: available in the new black color and featuring the proven 8mm thickness of memory foam, this chamois is the right compromise between comfort and performance.
3D waffle: A patented, three-layer perforated foam that increases breathability and eliminates excess weight.
goldenGate: A patented technology that interrupts the seams along both side panels of the seat pad, offering more three-dimensional freedom of movement in this delicate area subject to rotational movements.
Y7 bibTech brace: Wide, flexible straps converge at the upper back in a Y-shaped design, creating a stable, flat structure that disappears between the shoulder blades.
Stabilizator V3: Back stabilizer made with a solid mesh structure that provides limited vertical elasticity. Includes MILLE GT line graphics and climaCode details.
Reflective strips: Apply to the back of the calves for greater visibility.
regularFit: Optimized for complete comfort in the racing position, with a more relaxed fit than racingFit, it behaves like a second skin.
