The next 100 years won’t look like the last 100

As floods and fires sweep across entire countries, we’re radically underprepared as a species for the speed at which change is taking place. But while we’re entering a new normality, we’re not about to suddenly evolve the ability to resist fire or live back in the oceans. So our survival systems need to adapt – from emergency planning and infrastructure, to our architecture and clothing. Of all of these, clothing is going to be the fastest.


Designed for an unpredictable world

It used to be just adventurers or the elite military who would be exposed to perpetual threat. But as risk becomes more commonplace, the clothes on your back need to do more. They still need to be soft, comfortable and warm, but they should be designed with extreme performance capabilities. So all our 100 Year gear is made from materials with properties that normal clothing simply doesn’t have. They’re built to cope with whatever the next century holds.


Wear it like a regular sweatshirt

The idea for the 100 Year Sweatshirt was to make it look and feel like a regular sweatshirt. So it’s designed to have a loose, relaxed fit. The inside is a warm, brushed fleece. And the material we use to build it looks and feels just like regular cotton. All of which makes it perfect to chill out in. It just happens to be the toughest sweatshirt ever built at the same time.


A soft sweatshirt built for tough conditions

Sweatshirts aren’t normally known for their toughness and breathability, or their ability to repel wind, rain and fire. But the 100 Year Sweatshirt is built for the harshest environments on Earth and is the most weatherproof sweatshirt you’ll find. While the outside can handle water and flames, the inside is a soft, windproof fleece that keeps you warm, dry and comfortable.

Fireproof and durable

You don’t expect a sweatshirt to be one of the toughest pieces of clothing you can put on. But the 100 Year Sweatshirt is fireproof, durable and abrasion resistant. Despite this it doesn’t feel like any tough, fire-resistant fabric that’s ever been made before. Instead it’s comfortable enough to spend the rest of your life in.

The outside is water repellent

Our 100 Year gear has always been built to be highly resistant to things like fire, time, water and abrasion. So as well as repelling fire, the 100 Year Sweatshirt also repels water. While most sweatshirts soak through as soon as rain hits them, the outside of the 100 Year Sweatshirt is water repellent. Light rain will simply roll off it, keeping you drier for longer.


4x more windproof than regular fleeces

The inside of the sweatshirt is made from an engineered fleece, and it’s this inner layer that provides the warmth and comfort you want from any great sweatshirt. It has an extremely compact structure that traps thousands of tiny thermal air pockets and makes it 4x more windproof than regular fleeces. It means you can either wear it just like a regular sweatshirt, or as your insulation layer. The tightly woven construction is what adds strength and durability to the sweatshirt, but without compromising on comfort.


An engineered fleece keeps your temperature stable

While the outside of the sweatshirt keeps out the rain, and the inside keeps out the wind, the 100 Year Sweatshirt still lets excess heat and sweat escape easily. It’s highly breathable and high-wicking. So when you start working hard the sweatshirt will let warm air and sweat out, helping your body cool down and keeping your temperature stable.

Built with Polartec technology

As well as being synonymous with outdoor gear, for the last decade Polartec have been developing flame resistant fabrics for the US military after their uniforms began melting in the intense heat of IED detonations. They work with military partners to develop combat-ready layering systems that protect soldiers from sudden heat sources in hostile territories. Our aim was to let anyone benefit from this technology. So we worked with Polartec to build our 100 Year Sweatshirt from scratch.


How it fights sudden fire

The material the 100 Year Sweatshirt is built from is designed to protect you in the most dangerous situations, from flash fires to arc flash. A flash fire is a sudden, intense fire that combines high temperatures and short duration with a rapidly moving flame front. An arc flash is a type of extreme electrical explosion that’s capable of generating temperatures of 19,400°C, which is four times hotter than the surface of the sun and can burn skin and set clothes on fire even at a distance.


The sweatshirt stretches in every direction

Despite being tough, fireproof and water repellent, the entire sweatshirt is built with four way stretch. Which means it can stretch in every direction and there’s no move you can pull where it will restrict you. Whether you’re climbing a mountain, setting up camp or watching TV, it’s engineered to work with you and never get in your way.


The origins of the 100 Year Sweatshirt

The 100 Year Sweatshirt wouldn’t exist if we hadn’t made our 100 Year Hoodie first. In 2017 we made version 1 of the hoodie from the same materials found in spacesuits and body armour. Four years later we’re now on version 3 and it’s capable of combating every element on Earth. While it’s always been fire and abrasion resistant, it’s now weatherproof too, to protect you against snow, wind, rain and cold. The idea for the 100 Year Sweatshirt was to offer the same high-tech performance capabilities in the simplest possible design.


Part of our 100 Year range

Our 100 Year Sweatshirt turns one of the most comfortable pieces of clothing into one that can protect you at the same time. It sits alongside our 100 Year Pants that are made from a material so tough it was originally built to enable the military to walk through burning buildings; our 100 Year Jacket, which is the most waterproof jacket on Earth; and our 100 Year Vest, which is fireproof, water repellent, and comes with enough pockets to carry your life with you. Worn together this system will protect against almost anything.
