The Ultraz EVO is the warmest, most protective winter riding jacket by Assos to date. It’s constructed with a blend of NEOS softshells and insulating RX fabrics to keep you as warm, dry, and shielded as possible in the most demanding weather. If you feel the cold this is THE jacket for you!
Tested in the toughest winter weather, the Ultraz Jacket delivers maximum warmth and protection. At the wind-facing front and upper back panels, Assos has used NEOS Light textile—a superlight 3L softshell with PU bonded membrane that’s water-resistant and 100% windproof—to ensure this element-facing section of your upper body remains fully protected from snow, rain, road spray, biting winds, and low temperatures. Added warmth has been achieved by adding a highly insulating, breathable brushed RX Heavy on the interior, ensuring your core remains warm and bone dry.
Assos has used the thinner NEOS Ultra on the sleeves—also deployed in the two-layer twinDeck construction—with an insulating 652.RX treatment on the interior for added protection and comfort. At the cuff, you’ll notice these two materials aren’t sewn together, which lets your gloves seamlessly integrate between the layers for streamlined comfort. Specific to the women’s version, the full back panel is made with the 3-layer NEOS Medium for added warmth.
By strategically applying three “weights” of NEOS softshells to the Ultraz, Assos have ensured you get the right amount of protection where you need it, while simultaneously maintaining breathability and increasing weight-savings throughout. The position our bodies take on the bike—combined with the intended riding conditions—inform these material selections, knowing that deep-winter riding calls for absolute attention to detail in how your apparel fits and functions.
