Back on Track horse sheets and blankets all work the same and can benefit all horses- from pleasure, to race horses to Olympic horses in every discipline. These products are made with our state-of-the-art Welltex fabric which reflects your horse's own natural body heat thereby creating a soothing infrared thermal warmth. Not to worry though, the horse will not get over heated, but sweating can result that will loosen and relieve sore and inflamed muscles. The thermal warmth increasesblood circulation which leads to muscles recovering quicker, staying looser and becoming less easily inflamed. The sheets/blankets can be used like a liner under your own blanket when it is cold out. Back on Track's Welltex material will never lose its effectiveness even if the products end up in the dryer. We recommend that you hang dry them as they can become stiff and less comfortable if they dryer is too hot.
