This is our most common question! The empty vest, including the piping and pump, weighs 1 lb 12 oz. The 6 oz battery pack fits comfortably in the pouch at the back of the vest. We recommend adding one 16 oz frozen ice core (1 lb) and 16 oz of cool water to the reservoir for optimal circulation.

One Ice pack with a special anti-thawing, non-toxic gel is added to the vest reservoir which then gets filled with cool water. This creates a fully enclosed system that routes the water flow around the front and back of the vest along the lines (shown in blue on the product image, but not visible on the actual vest).

Turning the vest on starts the pump system. As the cooled water comes near your body, it wicks heat away from you and re-cools it as it passes the ice pack in the reservoir. The BPA-free polyethylene (PE) reservoir assists in maintaining a cooler temperature to optimize the time that the ice pack stays cool. Simply replace the ice packs as needed by keeping them in the freezer, ready to swap.

The 10,000 mAh battery is in a self-enclosed water resistant pouch to help to protect it.
