On their Facebook page Routt County SAR says, “There is a saying in the mountains that “cotton kills” because when it becomes wet it looses any insulating properties and can quickly lead to hypothermia. Wool or synthetics like polyester should be worn since they will keep you warm even when wet. This is true in both the winter and the summer. Stay safe and have fun out there!”
