Thule Stacker Carrier - $122.95

The Stacker is a standby for hauling whitewater kayaks on your roof rack. Evolved considerably from its beginnings as an undistinguished vertical loop, the Thule Stacker now has a separate upper bridge that makes it easy to tie your boats down. The Stacker holds up to four boats and folds down for a cleaner look and reduced wind profile when not in use. - $122.95
