Cool Comfort® Performance Cooling Hidden Vest

The vest may be used in different ways after first hydrating the special water-absorbing crystals:

• Straight from the freezer or from a cooler of ice water. The vest will cool for up to 2 hrs. in this method.
• At ambient temperature as an evaporative cooling vest. Water causes a natural cooling effect as it evaporates, which can provide many hours of cooling relief in lower humidity.

To use the vest:

• Simply submerge in water, gently squeeze and towel dry. Use immediately, or allow the garment to dry to the touch and then chill in a refrigerator or freezer for a higher level of cooling. 
• The special water-absorbing crystals will soak up many times their volume in water and then hold the temperature of the water an extended period of time.
• The weight of the garment may be adjusted by how long the garment is allowed to soak in water.
• Submerge garment in water to reactivate. 
• Please note: cooling times are estimates and will vary depending on climate, body metabolism and activity.
