We created the first-ever puffer jacket for the tropics. It used a beer-powered cooling system to reduce the body's temperature by up to 5 degrees Celcius. We turned a piece of winter wear into something that could be worn in the summertime, or in tropical heat.

The Summer Puffer applied the same technology that NASA uses to keep astronauts cool in space - a liquid cooling garment (LCG) - and modified the system so that the source of the cooling would be a can of Tiger Beer. The jacket reduces the body's temperature by up to 5 degrees Celcius.

The puffer jacket is one of fashion’s hottest items amongst Gen Z and millennials across Asia but there’s one challenge: it can’t be worn in the heat of the tropics.

In the world of Gen Z fashion, puffers are blowing up.

But they're too hot to wear in the tropics.

So to engage with a Gen Z audience that was increasingly disconnected from the beer category, Tiger Beer created the first-ever puffer jacket for the tropics.

This was a puffer jacket with a cooling system, powered by ice-cold Tiger Beer.

Bringing to life the intrinsic qualities of the product in a whole new way.

We took inspiration from the same technology that NASA uses to cool space suits, what's called a liquid cooling garment (LCG). This is a form-fitting garment that removes body heat from the wearer by pumping a coolant around the body, focusing on specific areas where the arteries are closes to the skin. This enables the coolant to siphon off heat from the body. In our case, we stored a can of ice-cold Tiger Beer in a cooling table and circulated water around the system as coolant. The beer cooled the water, which then cooled the wearer.

Developing this system took significant experimentation to work out the best materials possible, as well as the best arrangement of tubes to maximise the cooling effect both in terms of temperature reduction and duration.

Using the designs developed, we can continue to produce more jackets, which can be distributed to Tiger Beer markets across the world. But more than that, we think that creating a climate-controlled piece of outwear raises challenging questions about the future of fashion, especially given the impact of climate change on our world. Will it one day become a norm to have clothing with in-built cooling systems?
