Waterfallproof Parka

The next megastorm is on its way

Megastorms hit California alone every 150 to 200 years, and it’s now 160 years since the last one. In December 1861, deep layers of water vapour known as atmospheric rivers formed high above the Pacific Ocean, before hammering California, Oregon and Nevada with rain, snow and hail for 45 days straight. Entire settlements were swept away by rivers which didn’t exist just a few weeks before. By January the floods stretched for hundreds of miles, and all 29,000 square kilometres of the Central Valley were submerged under three metres of water.

What storms of the future will look like

The Great Flood of 1862 is the worst known natural disaster to have hit the US since the Europeans arrived. But instead of being a freak event, it’s a glimpse into what Earth’s future might look like. Samples of sediment from Californian riverbeds have shown that these extreme weather events have happened every couple of hundred years. And as the planet heats up, we’re going to see more of them. Researchers have been creating models of the next potential megastorm, predicting wind speeds of 200km/h and rain so heavy it could result in flooding deeper than 6 metres.

Waterfallproof Parka

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.

Why we’re making waterfallproof clothing

As we face life on Earth with new categories of weather, we’re going to need new categories of clothing. With floods and fires sweeping across cities and states, “waterproof” is not enough. Describing it as raining doesn’t quite cut it when you see houses and cars floating down the road. While technology will help us predict and track storms with greater precision, knowledge is meaningless without the right emergency planning, flood defences, architecture and infrastructure. And our clothing needs to adapt at the same time too.

Waterfallproof Parka

Built with a Swiss supermaterial

The Waterfallproof Parka is designed to combat the megastorms of the future, where crazily intense rainfall becomes the norm. Highly waterfallproof, windproof and breathable, it’s constructed with an advanced 3 layer Swiss material from Schoeller, with an intelligent membrane that opens and closes in the heat, and self-drying nanotechnology borrowed from plants. Building the material alone requires a total of 28 separate construction processes.

Water rolls off it like a lotus leaf

The outside of the Waterfallproof Parka 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.

Waterfallproof Parka

How nanosphere® technology works

When a water droplet lands on a normal flat surface, it sticks easily and quickly begins to absorb. But when water hits the surface of the lotus leaf, it can only balance on the peaks of the tiny bumps, meaning any movement or a breeze will cause the liquid to simply roll away. The outside layer of the jacket replicates the leaf’s microscale bumps using Schoeller’s nanosphere® technology. The bumps are completely imperceptible to the naked eye, but allow the jacket to resist water, oil and dirt.

Waterfallproof Parka

Highly waterproof and highly breathable at the same time

The issue with creating something crazily waterproof is breathability. The more water can’t come through one way, the harder it is to let it come out the other. A rubber wetsuit for instance would never let any rain through, but if you tried to go for a run in one you might pass out as it won’t let heat or sweat escape efficiently. So the middle layer of the jacket uses Schoeller’s c_change® membrane. Instead of remaining static, the membrane can open and close to respond to different weather conditions as they happen, while remaining permanently waterproof and windproof.

Waterfallproof Parka

How the membrane works in the cold

This c_change® membrane mimics natural structures like flowers and pinecones, opening and closing in response to changes in temperature, humidity and sweat. It’s designed to keep you at a consistent temperature by combining really high breathability with heat retention. While it can open up like a series of microscopic vents to let heat escape, in the cold it closes itself like a protective barrier to stop heat leaving. So as soon as the temperature drops, or you stop moving, the membrane contracts to insulate you and retain heat close to the body.

Waterfallproof Parka

How the membrane works in the heat and wet

As the air temperature rises, the membrane opens up so that excess sweat and heat can escape through the jacket. But while the membrane’s polymer structure opens up to become extremely permeable to water vapour leaving the body, it remains completely waterproof on the outside. It means that even if you held a jacket under a downpour in extreme heat, the jacket will only ever let the water through one way, while still letting heat pass through it.

Waterfallproof Parka

Fitted with a watertight chest pocket

While every zipper on the Waterfallproof Parka 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 scuba diving 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.

Waterfallproof Parka

Waterproof detailing throughout

Every detail of the jacket is built for extreme waterproofness. All the seams are fully sealed, and critical seams are reinforced with giant welded bartacks for strength. We’ve also engineered out seams at the shoulders to eliminate the chance of water finding its way in. And the jacket is designed with a long fit to help keep the top half your legs dry in the wettest conditions.

Waterfallproof Parka

Deep pockets and storm flaps for harsh weather

Two massive side pockets are fitted with waterproof zippers and covered by storm flaps which fasten shut with a metal press stud. The pockets are deep enough to let you tuck in up past your forearms if you’re being battered by rain. The two-way front zipper is water-resistant and protected by a large external storm flap which fastens down with tough metal snap fasteners. On the inside there’s an internal storm flap to protect you from wind and rain.

Waterfallproof Parka

Cuffs that work like a Velcro belt

You can tighten the cuffs as hard as you want thanks to a simple Velcro belt. The Velcro slides through a loop that you can then pull tight to create a seal around your wrists or gloves to protect you from the elements.

Waterfallproof Parka

A hood built for protection

When the weather turns hostile you’ll find an internal fastening system either side of the hood and another adjuster at the back, so you can tighten it fast. The jacket comes with a high collar to insulate you in the harshest conditions, and it’s lined with a soft, brushed fabric against your neck, nose and mouth.

Waterfallproof Parka

Engineered for movement

The jacket will stretch with you whatever you’re doing. But instead of relying on elastane, we use an advanced weaving process which creates mechanical stretch to achieve the same effect. Articulated sleeves follow the natural shape of your arm. And you’ll find two long side vents on either side of the jacket to keep air flowing around your body and make sure you never feel restricted.
