Rain (waterproof) blankets are outdoor blankets without padding (grams), so they have no particular properties in terms of heat conservation. Their first and foremost purpose is to protect the animal against inclement weather (rain, etc.), so they are most suitable for mid-season use (autumn and early spring during periods of heavy rain). 

 

Century's Ultra 1200D Summer Turn Out waterproof rug offers 1200D polyester waterproofing. Its silky nylon lining and crossed surcingles make this waterproof blanket highly effective. D-rings at the neck allow a neck to be attached in heavier rain to protect the entire neck and mane.
