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 front pouch. For best performance, we recommend adding one frozen ice plate (~1 lb) and 16 oz of cool water to the reservoir.

Insert one reusable ice plate into the vest reservoir, then fill with cool water. This creates a fully enclosed circulation system that routes the water around the vest through integrated channels (invisible from the outside).

Once turned on, the internal pump moves cooled water across your body, pulling heat away and recooling it as it passes the ice plate. The BPA-free polyethylene reservoir helps maintain the ideal cooling temperature. Just swap out the ice plates as needed to keep the relief coming.

The 10,000 mAh battery is housed in a water-resistant pouch to help protect your gear while you're on the move.
