If you've ever visited the Scottish Highlands, you know it can be very cold wet, muddy, and rugged. Kilts in their original form, were made from wool and allowed for easy moving when riding horses as well as traversing the terrain. They also served as a weapon during combat. Wool is ideal to be used outdoors due to its inherent water-repellent qualities. Therefore, kilts made from acrylic wool were able to repel moisture and held their shape. The extra fabric wraps around the wearer's waist made sure you always had a mat or blanket for sleeping.
