These padded adjustable thigh braces provide more comfort and grip over the standard knee tabs which are non-adjustable. Two screws tighten into a track of captive nuts under the cockpit rim, and once loosened, the braces can be moved fore and aft, slide in and out of the cockpit area, and can be angled to suit your seating position.
We recommend you have the thigh braces as far apart as possible to maximise the space at your knees when paddling knees-together, but if you anticipate you will need an extended period of bracing, before leaving shore, you can adjust for extra grip.
