Internal Rev'it Cool Challenger Waistcoat Black Hyperkewl

When your temperature rises, fatigue begins to make you feel and this affects the control of the bike. The Liquid Refreshing Vest helps using Hyperkewl ™ technology that works by absorbing and storing water to release it slowly with a natural evaporation process.
This vest helps motorcyclists stay cool and in control. For best results, combine it with a well-ventilated jacket. The vest remains active for about six hours once activated and has a lateral zipper for easy access.
Instructions for Use of Hyperkewl ™ Refreshing Products Before first use, soak the article in water, gently tip it and let it dry completely. This is necessary to activate the refreshing fibers.
Note that the article after the first activation may appear brittle because of the fiber migration. This feeling, however, is lost to the next immersion.
