Collection: Waistpack Self-contained Cooling System

This is the lightest and smallest cooling system COMPCOOLER has to offer.  It combines a tubing-lined vest with a liquid cooling system housed in a waistpack to form a self-contained and convenient thermal regulation device. It includes a 1.5-liter removable water/ice bladder, miniature circulation pump, 7.4V 2200mAh rechargeable battery, and On/Off switch. Cooling energy is provided by removing the bladder from the system, filling it with water and placing it in a freezer.  Once frozen, the bladder is easily re-attached to the system, and with a charged battery pack, Users turn the switch ‘On’ and the pump circulates cold water in a continuous loop between the bladder and vest.
