Equine Therapy Systems Infrared neck and back wraps use Red Light Therapy to speed up and enhance healing in the neck or back (or any area where it can be wrapped around including the belly, legs, flank etc) of your horse.
Red Light Therapy (also called Infrared light, Photo-biomodulation or photonic therapy) has been scientifically proven to be beneficial for treating chronic pain such as arthritis, navicular and laminitis, sore muscles, wounds, tendon injuries, skin conditions including hair loss, colic and hoof abscesses. It also improves immunity, reduces inflammation and helps enhance performance.  Read more about it here
Red Light Therapy (RLT) is a technique that uses low-level wavelengths of light to treat a multitude of issues. The use and popularity of RLT has grown due to the enormous healing capabilities, and many doctors and veterinarians around the world believe it to be a safe, effective method for treating a broad range of health conditions in people and animals.
How does it work?​
Red Light Therapy treatment involves the use of a low-level red light, using wavelengths in the range of 600-850nm to penetrate directly through the skin. These wavelengths have the ability to transform into cellular energy and ‘kick start’ an increase in adenosine triphosphate (ATP) production which causes a boost of energy to the cells, and also the stimulation of collagen production. Red light therapy affects all layers of the skin, and can reach blood vessels, lymph vessels, nerves, hair follicles, and soft tissue, dependent on which part of the animal’s body the red light is being projected.
These boots have been developed by ETS in conjunction with other top international Equine Therapists in order to establish the most efficient and effective designs to best treat your horses.
Use for 15 to 20 minutes daily - you should start seeing improvement within 2 weeks.
The  wrap comes with its own battery pack and charger. It comes in a sleek zip up waterproof EVA case. 
An extra extension band is available if you want to use the wrap across the body of your horse. (The maximum diameter that the wrap can go around without an extension band is 123cm). The extension band is 95cm long.
