Lets start with the part that gets the most questions - the unique elastic cradles. Both the reins and the cheekpieces have elastic cradles that the bit rings sit in - this helps suspend the bit and give an elastic feel down the rein as well as helping relieve any tension or blocking at the poll as a result of the horse feeling 'trapped'. You can see them clearly in the image below.
The cradles are selectable - the bit ring can be tucked behind them rather than sitting in the loop depending on your horse's preference and training. Recently, the cradles became both FEI and BD legal.
The headpiece is another key feature of the bridles - and looks quite difference to the more traditional bridles you might see. The headpiece is gently shaped and cut back behind the ears, its also wider than a traditional headpiece to give a wider distribution of pressure across the poll and avoid pinch points. Some of the designs have an extra 'air gap' in the centre which avoids the most sensitive part of the poll.
In part two, we'll take a look at the different styles of noseband and how they can help.
