How PolarPillow Works:

• PolarPillow's endothermic gel technology uses the coolness of ambient room temperature to dissipate your body's heat.
• PolarPillow feels cool within 10 seconds of contact.
• PolarPillow stays cool for approximately two hours of contact (just enough time to fall asleep), but it gradually warms over the course of a night's use as it takes on your body's temperature.
• When not in use, PolarPillow's coolness will re-energize within 20 minutes of exposure to an air-conditioned room (about 75 degrees).
• PolarPillow contains more than 200 ounces of cooling gel (about 12 lbs). The liquid gel is heavy and PolarPillow weighs much more than a regular pillow.
• PolarPillow requires no set up, maintenance, electricity, refrigeration or water.
• PolarPillow fits in a standard pillowcase.
