I have no idea I just saw them a while ago. I have rhuematoid arthritis and am struggling to stop the reins slipping thro my fingers, have tried every normal rein type and obviously some are better than others and I thought these would be helpful
How do the bridging reins work ? would they be suitable?
Are they the Ernest Dillon de boiz reins? You set them at the length you need and it's meant to maintain your contact? http://www.deboiz.com/html/reins_0.html
