Are Tough1 blankets and sheets waterproof?

We cannot guarantee that our blankets and sheets are 100% waterproof, 100% of the time. This is due to the nature of needing to allow some breathability for the blanket/sheet, thus preventing your horse from being a sweaty mess. We do caution that blankets worn in heavy rain and snow fall for extended periods of time will become damp eventually. We recommend allowing turnout blankets to have time to fully dry out after being used under significant amounts of precipitation.
