Original 100 Year Sweatpants
Weatherproof sweatpants that keep out fire, wind, snow and cold.
- Designed to look and feel like normal sweatpants
- They repel rain, wind, snow and fire
- Soft, engineered fleece inside
After spending two years in R&D rebuilding our 100 Year Hoodie to combat fire, rain, wind, snow and cold, we decided to take the same technology and use it to make a pair of weatherproof sweatpants.
While the 100 Year Sweatpants look and feel like a normal pair of sweatpants, they’re infinitely tougher, as they’re built from a material that started life in a warzone. Constructed from a three-layered fabric originally developed for the elite military, every pair is milled in the US before being manufactured at one of the most technologically advanced factories in the world.
With a soft, warm, engineered fleece next to your skin, water repellent membrane and fire repellent outer shell, these warm winter sweatpants are designed to last for the rest of your life.
The pants are made from three layers sandwiched together
If you looked at a cross section of the pants, you'd think you’re just looking at a single layer of fabric. But just as you’d find with any high-performance jacket, it’s actually three separate layers sandwiched together and performing three distinct roles. The outer layer is a stretchy, fireproof and windproof softshell. The middle layer is a waterproof membrane. And the bottom layer next to your skin is a soft, engineered 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.
The outside layer is fire repellent
Even on its own the outer layer of the pants would be one of the toughest pieces of clothing you’ve ever worn. Highly durable and abrasion resistant, it’s also fire repellent. Yet despite this it doesn’t feel like any fire-resistant fabric that’s ever been made before. And that’s because the two layers beneath it help turn it into a pair of sweatpants comfortable enough to spend the rest of your life in.
How it fights sudden fire
The material the 100 Year Sweatpants 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.
Built with Polartec technologies
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 rebuild our 100 Year Hoodie from scratch, then we used the same technology to make these pants.
The middle layer keeps out rain and wind
Sweatpants don’t normally come with membranes. You usually only find them in high performance outdoor jackets. But these are 100 Year Sweatpants, so they have one. And just like any good ski jacket or running jacket, the membrane is there to keep the rain and wind out, while letting excess heat and sweat escape easily.
An engineered fleece sits next to your skin
The inside of the pants is made from an engineered fleece. And it’s this inner layer that provides the warmth and comfort you want from any sweatpants. The fleece is built with a grid structure which creates thousands of tiny air channels. These are designed to increase breathability and trap warmth, while subtly decreasing the mass and weight of the pants. The fleece is also hydrophilic, so it rapidly absorbs sweat and transfers it to the outside of the pants.
Built for the harshest environments on Earth
Whether you’re taking on a mountain or the whole of Netflix, you’re going to need some really warm, comfortable pants to wear. Sweatpants are not normally known for toughness, waterproofness, or breathability. But all our 100 Year gear is made with materials that have the kind of properties normal materials simply don’t have, and the 100 Year Sweatpants are no different. So while these are the toughest and most weatherproof sweatpants ever created, they’re also perfect to sit back and relax in.
Wear them like your regular sweatpants
The idea for the 100 Year Sweatpants was always to make them look and feel like any other sweatpants. So they’re designed to have a loose relaxed feel. And the inside of the pants is a warm, cushioned fleece. The pants have four large, super-practical pockets for carrying extra gear. There are two large front pockets, and two more at the back. The zippers are all rubberised and waterproof. There’s a zipped front fly, and a drawcord waist with heat-moulded rubberised ends.
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.
