Waterfallproof Puffer
Built for a future of megastorms, where ‘waterproof’ is not enough.
- Highly waterproof to over 40,000mm
- Synthetic insulation fused with aerogel
- Fitted with a watertight chest pocket
As we face life on Earth with new categories of weather, we’re going to need new categories of clothing. With extreme weather events on the rise for the last 40 years, and floods and fires sweeping across cities and states, “waterproof” is not enough.
The megastorms are coming. Describing it as raining doesn’t quite cut it when you see houses and cars floating down the road. So we’ve started working on clothing designed for a world of ultraviolent weather – a world where the sky starts acting more like the ocean, and atmospheric rivers dump tidal waves of water down on towns, cities and villages.
The Waterfallproof Puffer is designed to combat the megastorms of the future, where crazily intense rainfall and snowstorms become the norm. Highly waterproof to over 40,000mm, water can’t even stick to the outside of the jacket. It comes with a watertight chest pocket that we borrowed from scubadiving gear. And the insulation is embedded with aerogel – the lightest solid material in the world – to keep you warm down to -40°C.
Technical Details

Water rolls off the outside like a lotus leaf
The outside of the Waterfallproof Puffer mimics one of nature’s most brilliant pieces of engineering – the lotus leaf. Over millions of years the lotus leaf has adapted to life constantly surrounded by water. Although the surface of each leaf looks completely flat, it’s covered with a complex landscape of microscopic bumps which helps it stay clean and dry.


Built with a Swiss supermaterial
You have to combine lots of different technologies to make a high-performance material this waterproof. Which is why the material we use for the outer shell requires 28 separate construction processes just to build it – and that’s before you even get to the insulation underneath. The outer shell is an advanced 3 layer Swiss material from Schoeller that’s highly waterproof and windproof. The outermost layer uses a self-drying nanotechnology borrowed from plants. Underneath it there’s an intelligent membrane that opens and closes as it reacts to temperature.
The lightest solid material in the world
Aerogel is only three times more dense than air – which makes it the lightest solid material in the world. For contrast, water is 830 times more dense than air. To make aerogel you take silicon gel and put it through a process called supercritical drying, which slowly extracts the liquid part of the gel without collapsing its structure. What you’re left with is a porous, sponge-like material that’s made up of 99% empty space.

Fitted with a watertight chest pocket
While every zipper on the Waterfallproof Puffer is built to cope with extreme volumes of rain, we’ve fitted the jacket with a chest pocket that can survive total immersion in water. Even if you’re wading in chest deep water, anything inside it will stay dry. It’s built with an incredibly heavy-duty waterproof zipper that looks a bit like a rubber anchor and is normally only found in scubadiving gear. Just as no water could get in, no water could get out. So if you’ve always wanted to take your pet goldfish out for a walk, fill up the pocket and now you can.


Regular storms are turning into megastorms
The number of extreme weather events has been rising for the last 40 years and that trend is set to continue. Higher global temperatures create more evaporation, which leads to more moisture in the atmosphere, creating heavier and more intense rainfall. So while the risk of the next megastorm increases with every year, regular storms are intensifying around the world at the same time. Every year we see more Category 5 hurricanes – the most severe and destructive you can get.


Size + Fit
The Waterfallproof Puffer is designed with a loose fit, with plenty of room for other layers underneath. If you prefer a closer fit, we recommend you go for the size down.
