Winter training on the open roads is not just a test of your resolve, but it's also the season to experience cycling on deserted roads and climbs whose chilled pavement and snow-lined shoulders turn away the more fragile cyclist. Assos' Mille GT Ultraz EVO Winter Jacket insulates your core on such rides and protects your motivations against harsh winter climates as you churn out the base miles. Updated to add increased protection and warmth throughout the entire jacket, Assos starts with the front and upper back -- which face winter head-on -- and combines their triple-layered NEOS Light and RX Heavy fabrics for windproofing and water-repellency. The sleeves are fortified with the breathable yet still winter-ready, two-layer NEOS Ultra and 652. RX fabric, while the back panel uses a three-layer, winter-proof, breathable soft-shell, NEOS Medium. Assos looks at the entire system as combining the highest-performing materials to meet the required goals of keeping you warm and protected as you train. Assos uses targeted stitch patterns to ensure a full range of motion in the riding positions while the center-weighted pockets are held tight and stabilized for comfort. The Tripe Ramp pockets create "lids" over your cargo to add security and peace of mind, as you don't want to lose your phone in deep-winter training. The full-length zip helps manage overall heat buildup, and the regular fit of the Mille GT Ultraz accommodates your favorite baselayers without adding bulk that would catch in the winds.
