Horses Turned Outside without Shelter - Turnout Sheet and Blanket materials are waterproof and designed to keep your horse dry, however if your horse is turned out in a field without a run in shed or shelter during prolonged rain or heavy downpours your horse may still get wet especially in the neck and tail areas. When blanketing your horse it is critical to monitor the fluctuating climate and temperatures even with a blanket that is waterproof and breathable. The wicking properties of a breathable blanket are designed to wick away normal body heat, when a blanket is too heavy the heat and moisture cannot be wicked away fast enough causing your horse to sweat. The temperature and the length of your horse's coat will determine what weight of blanket you should use. For this reason, most people who choose to blanket horses have several articles of horse clothing that offer varying levels of warmth.
