ChestnutBuy Now The wool hemp upper of the Chestnut model creates a pleasantly warm feeling for our feet thanks to its natural climate regulating properties. The combination of hemp from VirgoCoop (40%) and virgin wool (60%) creates a lively shimmer on the textile surface and gives the fabric an especially smooth look. The upper transitions smoothly into the heel loop for an effortless slip into the lined Chestnut. Off into wooly warm adventures!
