Men's Hyperkewl Cooling Sport Vest

The TechNiche International Men's Hyperkewl Cooling Sport Vest provides evaporative cooling to keep the wearer cool in hot weather. It must be worn over clothing and works best with thin, lightweight clothing. It is not recommended to wear it under clothing. The vest does not come with ice packets; it must be soaked in water to activate. It may leak if not wrung out properly, and it works best in windy or fan-moving air spaces. It has received several positive reviews for its effectiveness in keeping the wearer cool for several hours. However, some users have experienced decreased effectiveness over time or in high humidity. It is important to follow the directions, and sizing accuracy varies. It is also not recommended for doing strenuous activities that may cause the wearer to become wet and uncomfortable.
