I love the dura tech cooler that sstack sales. Its made of wool and acrylic. The wool gets the horse dryer faster. But the acrylic makes it better so you can wash it and it will keep its shape unlike the solid wool blankets. It also wears very well. I've had mine for years and used it alot and it still looks like new. They also run very well in sizes. Not to mention they are very well priced.
