How does it work?

Our design is simple. Fill the bladder in the back pack with ice, fill a quarter of the bladder with water, plug in the usb for power, connect the back pack to the shirt, and hit the on button! The built in pump will flow the ice water through the shirt keeping you cool while you work, hit the trails, go fishing, or anything you can think of!

What is included in the box?

Your Cool Mate Starter Pack comes complete with everything you need for the start of your expandable cooling experience. This includes our Cool Pack, One shirt, and a battery pack to kick start your journey into a cooler summer

What is expandable cooling?

We know that not every product is useful in every situation. That is why we created our expandable cooling range! Everything you see on our store can be mixed and matched to tailor your cooling experience anywhere you go.. You don’t stop, so neither should we!

How much does it weigh?

When the bladder is completely filled, it weighs around 3KG. It can be reduced to 2KG with less ice, however this will require the back pack to be refilled with ice or ice packs more often

Does it actually work?

During our testing in November, under a scorching 33-degree sun, we observed a remarkable drop in body temperature ranging from 3 to 7 degrees after just 2 hours of direct exposure. It's worth noting that the perceived coolness factor appeared even more pronounced than what was actually recorded
