Side Reins

Side Reins for Horses & Ponies

Improve your horse’s posture and balance with correctly fitted side reins.

Side reins are essential training aids used in lunging and long-lining to encourage a steady contact with the bit and correct head carriage.

Used correctly, they help your horse build strength, flexibility, and coordination—especially valuable for young, green, or rehabbing horses.
