100 Year Sweatshirt
Built for the harshest environments on Earth, it’s the toughest sweatshirt ever built.
- Outside of the sweatshirt is water repellent and fireproof
- Ultra-soft fleece inside
- 4x more windproof than regular fleece
Our 100 Year Sweatshirt turns one of the most comfortable pieces of clothing into one that can protect you at the same time. Sweatshirts aren’t normally known for their breathability, their insulating properties, or their ability to repel wind, rain and fire. But the 100 Year Sweatshirt is built for the toughest challenges on Earth and is the most weatherproof sweatshirt you’ll find.
While the outside can handle water and flames, the inside is a soft, engineered windproof fleece that keeps you warm, dry and comfortable. 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, while remaining highly breathable and high-wicking.
The entire sweatshirt is water repellent, built with 4 way stretch, and is 4x more windproof than regular fleece. So you can wear it as a high performance insulation layer, a protective outer layer, or just like a regular sweatshirt.
Technical Details

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.


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.
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.

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.
