The Nano Flex 3G fabric used across the garment utilises a combination of newly updated durable water repellent (DWR) treatment and mechanical heat treatment to give previously unheard-of levels of rain protection. Light rain beads off the fabric, keeping you dry when those inevitable rainy spells descend.

On the inside of the Nano Flex 3G fabric, a super soft finish and the optimal loft have been achieved through Castelli’s meticulous research and development. The fabric feels phenomenally comfortable against the skin and the loft traps just the right amount of air above the skin to keep your heat regulated over a wide range of autumn and winter conditions.
