The Ultraz Winter Jacket S11 was our most extreme winter jacket in the endurance line. The S11 EVO is the evolved version, updated with a warmer construction and a less restrictive fit. It’s still streamlined, with no added volume or excess material, but a more elastic construction and micro adjustments to the collar, shoulders, and chest create a sense of free movement that seems impossible for this amount of protection. Easier breathing, easier reaching into pockets, easier posture while off the bike.Ultraz protection begins with a twinDeck front panel comprising AIRBLOCK-EVO.888, a stormproof softshell, and an inner lining of HEATER, a waffle-structured insulator that traps micro pockets of warm air and actively channels moisture away from your body. The new sleeve textile, CORE Medium, fuses a thermal layer with a 3L softshell, a low-volume construction that nevertheless hits higher marks for insulation and elasticity than its predecessor.
The finer details
The main body textile is AIRBLOCK-EVO.888, a proprietary stormproof softshell developed for the Racing Series and featured here for its high elasticity and excellent breathability. Beneath it, the waffle-structured HEATER textile preserves a warm microclimate while promoting breathability. The sleeves feature CORE Medium, the most insulating of the CORE softshell family. Its breathable membrane and ECO water-repellent treatment shield an ultrasoft insulating layer, adding stormproof protection to warmth. RX EVO Plus panels constitute the back and underarms, adding breathability and elasticity while preserving dry warmth with thermal properties and an ECO water-repellent treatment.
