Men's Alé Thermo Shield winter jacket. On rides with climbs, descents, and restarts, Polartec® Alpha® active insulation helps manage changes in intensity: it retains heat while promoting the release of moisture and excess heat. The windproof outer layer with a DWR water-repellent treatment limits exposure to cold air and surface water. The R-EV1 line's close fit follows your position on the bike; a silicone gripper hem and anatomical raw-cut cuffs help keep the fit secure. Three back pockets keep accessories organized, while reflective details add visibility. For the Alé Thermo Shield men's winter jacket, the manufacturer recommends a temperature range of -5°C to 10°C—a guideline to adapt to intensity, weather conditions, and personal sensitivity.
