Description
Stormproof
The Assos Men's MILLE GT Ultraz Winter Jacket S11 EVO is a stormproof winter cycling jacket for the most extreme wet and cold conditions, updated with a warmer construction and less restriction across the chest, throat, and arms.
The Ultraz Winter Jacket S11 was the 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.
Features:
- Featured Fabrics: The main body textile is AIRBLOCK-EVO.888, a proprietary stormproof softshell developed for the Racing Series, 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, with a breathable membrane and ECO water-repellent treatment shielding an ultrasoft insulating layer. RX EVO Plus panels on the back and underarms add breathability and elasticity while preserving dry warmth with thermal properties and an ECO water-repellent treatment.
- Construction/Fit: Streamlined regularFit and body-contoured shaping reduce seams, eliminating friction for total comfort and easy layering.
- twinDeck: A double construction that layers thermoregulating insulation below a stormproof softshell membrane, adding protection in crucial areas.
- Reflective Detailing: Stripes on the pockets and logos are both reflective, increasing visibility in the low-light, overcast conditions when stormproof protection is most valuable.
- Triple Ramp Pockets: Flexible fabric panels sewn into the pockets secure and stabilize the contents while protecting against precipitation or road spray.
