This incredible towel is made from a blend of nylon and polyester (50/50). The premium cooling towels, with 50% nylon content, offer faster cooling compared to similar products made entirely of polyester or Dacron. The nylon fibres repel water, allowing for rapid evaporation upon contact. By utilising this evaporation process, Yeti cools down up to 15 degrees below the surrounding temperature in seconds. To activate it, simply wet the towel, wring it out, and tightly snap to remove excess water. It can be worn around the neck or head, providing natural and chemical-free cooling as long as it remains wet. Perfect for sports, jogging, biking, gym workouts, and outdoor activities, Yeti also serves as a sports or gym towel. It comes in a carabiner tube with complete instructions.
