This simple patented rein attachment has been developed to provide the correct starting point for a relaxed; balanced and obedient horse. The flexi-reinãâ design allows your horse to naturally flex at the poll and neck; encouraging him to relax as the uptake of elastic relieves any extra tension and pressure on the sensitive mouth area. Ensures improved results every time you ride; whether out hacking; schooling or during competition and is also invaluable whilst lunging. Largely eliminates pulling; jogging; leaning on the bit; head tossing; snatching at the reins and relieves tension. Two levels of adjustment: the first for general schooling/hacking; the second for stronger horses or for faster work where more control is needed
