How It Works:
The Fast|Cool Waistpack System pairs a tubing-lined mesh cooling vest with a compact waist-mounted cooling unit. Inside the belt pack, a 1.5-quart (1.5L) ice/water bladder, rechargeable battery, and miniature circulation pump work together to circulate chilled water (36°F-68°F) through four cooling zones on the vest.
The result: steady, even cooling that helps reduce heat stress, maintain focus, and extend endurance in hot, confined, or protective gear environments.
Portable Cooling. Simple Control:
The 7.4V 2200mAh rechargeable battery powers a quiet, efficient pump that continuously circulates water through the vest.
A three-speed flow control lets you adjust the system's performance to your needs - conserve ice on low, or maximize cooling when the heat spikes.
Flow rates range from 8.5 to 17 fl oz/min, giving you full control over comfort and duration.
Easy to Use:
- 1. Detach the 1.5-quart bladder with quick-connect fittings.
- 2. Fill with water and freeze.
- 3. Reinstall the frozen bladder and connect tubing.
- 4. Turn on and select your desired flow rate.
Cooling lasts 1–2 hours per frozen bladder, or longer with extra frozen replacements.
The battery operates up to 10 hours per charge, depending on flow setting and usage.
Extra bladders and batteries are available for extended cooling.
Built for Comfort + Movement:
The Fast|Cool mesh cooling vest weighs just 1.1 lbs (0.5 kg) and is made from soft, breathable fabric for comfort against the skin. A full front zipper and Velcro side tabs ensure a snug, secure fit for optimal cooling performance.
The waistpack unit adds only 3.3 lbs (1.5 kg), keeping the system lightweight and evenly balanced for unrestricted motion - ideal for industrial, tactical, or motorsport environments.
