Designed to thrive in colder climate conditions, these are the warmest and most protective bibs in the REV-1 series. Highly insulating, they maintain a constant cycle of heat generation (up to 1°C) to actively keep you warm, reduce heat loss and stabilize a consistent temperature. Constructed to follow your form on the bike, our Body Mapping insights informed the placement of specific panels, included windproof and water-resistant laminated ones that ramp up protection where needed. Your spine and lower back benefit from a raw-cut finish and soft mesh panels, engineered with specific levels of stretch to contour your body for comfort.
